It will be useful for any user to know how to disassemble a Samsung tablet in order to solve some problems themselves or simply clean the device, speeding up its operation.
Before moving on to the main part of the article with the preparation and step-by-step disassembly process, I want to warn you that I do not recommend doing this to people who have absolutely no knowledge of technology and have never disassembled anything.
Firstly, for beginners this may not work, and as a result the gadget may be damaged to such an extent that it cannot be restored.
Secondly, even with detailed instructions, it is easy to confuse any components or parts of the case, assembling or disassembling the device incorrectly.
Thirdly, if you act carelessly, there is a small risk of getting damaged yourself. Therefore, if you doubt that you can disassemble the device properly, then contact a tablet repair service.
Why do you need to open your smartphone?
The simplest and most important reason is to install a SIM card in a new, just purchased gadget, as well as installing or replacing an SD memory card, which is included in almost every Strike BQs phone. A micro-SD card allows you to expand the internal memory by another 128 GB, which is undoubtedly a plus.
Many smartphone owners reboot a frozen device by removing and reinserting the gadget's battery. The user may also need to open the cover to replace an outdated or non-functioning battery with a new one. In addition, if you decide to independently repair or replace parts in a gadget, you will not be able to get to the inside of the phone without removing the back panel.
So, let's look at a detailed algorithm of actions with which you can open the BQ phone and see what is in its internal part.
Troubleshooting other problems
In addition to problems with filters, the owner of a vacuum cleaner may encounter clogged impellers. It is cleaned dry. If you managed to remove the engine and you find wear on its brushes, you can replace them yourself and clean the commutator with fine sandpaper. If the fuse is blown, it is better to immediately take care of purchasing another vacuum cleaner, since its cost is slightly less than buying a new unit.
If you suspect a wire break, you need to test the voltage in the remaining nodes with a multimeter. After checking and finding the break point, the fault can be quickly eliminated with a regular soldering iron. Before checking, make sure that the vacuum cleaner motor is not de-energized: this often happens when the temperature sensor is triggered. If it turns out that the engine is de-energized, do not rush into checking and other actions. Most likely it's a matter of normal overheating. After the vacuum cleaner has cooled down, it will automatically restore its functionality.
Required Tools
Before you disassemble your Samsung phone, make sure you have the right tools.
- Mediator or regular credit card. Bonus cards from thin stores are also suitable.
- Phillips screwdriver PH. If you only need to remove the cover, this tool may not be needed, but to dismantle the microcircuit and other modules, such a screwdriver is required.
Older Samsung models are usually equipped with a removable back cover, but in the Galaxy line of recent years there are non-removable cases.
Preparation
Preparation before disassembling the Samsung Galaxy Tab 3 tablet (namely, this model will be given as an example below) includes reading this article to the end.
It is important to know that you understand what you are doing and why, and that all instructions are very clear to you. Otherwise, you may disassemble the device halfway and be confused about what to do next.
Next, prepare the necessary tools (more on this in the next heading) and choose a convenient place to work. An empty table with a couple of cups on it to collect small parts like screws works great.
Algorithm of actions
First, inspect your smartphone. At its upper end, to the right of the micro-USB connector, you will see a small recess, as if created so that the cover can be pryed off. Carefully insert your fingernail into this recess and slide it to the left, going along the part where the plastic case fits snugly against the glass of the smartphone display.
If you are unable to do this, while moving along the body with your free hand, lightly squeeze it on the sides so that the plastic bends and makes it possible to open the lid. Next, carefully run your fingernail along the entire perimeter of the smartphone several times, thereby opening the cover of the device.
The plastic panel may crack slightly when opening, and there is no need to worry - this is normal. Open the lid of the BQs 5020 Strike once, and you will easily do this operation again and again in the future.
Necessary tools and instructions for complete disassembly
If a person has experience in handling household appliances, he can already determine the cause of a malfunction in its operation by sound. When the bag is full, the vacuum cleaner hums or makes a characteristic hissing sound. In case of more serious damage to the engine or board, its sound becomes intermittent, dust begins to fall from all holes, and the smell of burnt wires appears in the room.
Depending on the nature of the problem, you may need:
When replacing filters, screwdrivers are needed to remove the rear grille, which is screwed on with self-tapping screws. When working with a board or wiring, you cannot do without other tools.
The problem may be discovered during disassembly of the case. Fortunately, the cause of the breakdown is not always the engine. If the relay-regulator connector is loosened or the board is simply damaged, you can fix the problem yourself.
Step-by-step instructions for disassembling the housing of a vacuum cleaner:
Locks and fastenings on Samsung vacuum cleaners can be screw or in the form of latches. The screw fastening is removed by unscrewing six dowels in sequence. You will find two of them on the front of the lid, and four more on the other side of the case, at the end and at the handle. The electronic board that controls the motor is protected by a top cover secured with plastic clasps. You can carefully pry them off with an old DVD or card. If you have a plastic ruler, try using it to move the latches to the side, holding them with a disk. So, they will not be able to return to their previous position, and the lid can be easily removed.
Attention! Samsung locks are very fragile, so you need to disassemble them carefully so as not to break them.
After “releasing” the control board, inspect it. If dust accumulates on the tracks, carefully clean, fix damaged connectors or replace the wiring in the right places. De-energize the system and remove the board. Before replacing wires, mark their connectors with a marker so as not to confuse them.
The procedure for disassembling the gadget
The disassembly instructions are suitable for most models of the Korean giant, but the location and number of screws, connectors and latches differ on different devices.
- We start by removing the back cover. If on your Samsung gadget this element is secured with only one latch, carefully push the cover up and remove it from the fasteners. This method of fixation is often found on older models. For the entire Galaxy line, carefully insert the pick or card between the cover and the body in the place where it is easiest to do so. Now move the card around the perimeter of the smartphone, carefully releasing the latches. After unlocking all fasteners, remove the cover.
- If the purpose of the procedure is to check the gadget for the presence of water, you can begin the inspection now. Make sure there is no liquid or oxidation on the battery or around the camera module.
- Now you can remove the battery. Carefully lift it up and out of the connector. There is usually a moisture sensor located under the battery. If its color is not white, water has entered the smartphone and the warranty is no longer valid.
- Remove the SIM card and SD card from their respective slots. Now separate the battery compartment from the case by inserting the card into the slot between these elements and running it around the perimeter of the device.
- Remove the heat-distributing metal plate from the board, if present. To do this, unscrew the mounting screws and pry it off with a flat-head screwdriver. Peel off the lock and volume buttons; they are usually secured with double-sided tape. Do not try to separate them from the microcircuit, just remove them from the end of the case.
- Let's start dismantling the board itself. Carefully remove all screws used to secure it. Their number varies on different smartphones and tablets. After unscrewing the screws, carefully unfasten the chip from the case, but do not remove it!
- Lift the board with a flat-head screwdriver or a pick and disconnect the screen cable from the connector. Disconnect other cables - speaker, microphone and connectors.
- Take out the board and set it aside.
At this point, the main stage of disassembly can be considered complete. If required, conduct a visual inspection of the modules.
When disassembling, always put small screws in a small container, otherwise they are easy to lose.
Removing display elements is a much more difficult task. Screen mounts can vary dramatically on different devices, so it’s best to entrust this task to professionals. You should not try to replace the screen at home without the necessary skills - such a procedure can end sadly for your device.
Disassembling the Samsung GT-C3752 DUOS cell phone
A Samsung GT-C3752 DUOS cell phone was received for repair with a reported malfunction - it fell into water, it is necessary to disassemble it and examine it for the presence of oxides. This, of course, is not the Samsung Galaxy Duos, but it’s still a shame for the phone. The owner removed the battery from the phone immediately after water got in, and this is a very correct decision.
Well, let's take it apart and see what happened to it after it got wet.
Removing the back cover:
Unscrew 4 screws:
Using a pick, carefully snap off the back of the phone along the entire length of the case:
It should look like this:
Using a flat screwdriver, carefully pry up the board:
Lift it up and disconnect the cable:
In the end it should look like this:
Unscrew 2 screws and remove the protective screen:
We carefully inspect the board - no traces of moisture. Well, let's disassemble the top part of the slider:
We unscrew the 6 screws (then I screwed them back, in my opinion, because you can easily disassemble the phone without unscrewing these 6 screws):
Unscrew the 2 screws from the bottom of the phone:
2 screws on top of the phone:
Using a pick, carefully open the upper part of the slider along its entire length (in this photo, by the way, you can see that 6 screws are screwed back in):
It turned out like this:
Lift the board with a flat screwdriver:
We carefully examine all parts of the cell phone. We see that there is a small oxide on the right side of the keyboard board. Remove it with a toothbrush soaked in alcohol. Everything else on the boards is clean. This is what it means to remove the battery in time. We assemble the phone in reverse order. We insert two test SIM cards (Tele2 and MTS). Include:
We make several incoming and outgoing calls. Everything works great - the microphone and speaker did not get wet.
All photographs were taken with a Kodak EasyShare C1530 camera.

How to remove the back cover of Samsung Galaxy
Samsung Galaxy repairs usually involve removing the back glass or back cover. Here's how to open the back cover of your Samsung Galaxy.
Samsung Galaxy models with snap covers
Most older Samsung Galaxy phones have snap-on back covers that are easy to remove. These include the Galaxy S, models S1 to S5, Galaxy J, models J1 to J3, and Galaxy Note , models Note 1 to Note 4.
To remove the back cover, simply locate the notch on the side of your Galaxy phone. Then use your fingernail or a pick to lift it up and off the phone until it comes off completely.
Samsung Galaxy models with stick-on covers
New Samsung Galaxy phones have back covers that are held in place using adhesive. These include Galaxy S S6 to S10, Galaxy Note models Note 5 to Note 10 and Galaxy A models A3, A5 and A9, as well as some Galaxy J . Their back covers can still be removed, but the process is a little more complicated:
- Use a hair dryer to heat the back cover and soften the underlying adhesive. Be sure to heat the edges and not the middle of the device.
- Place the suction cup on the rear window, then lift it up by prying the side seam with a pick.
- Run a pick along the seam to separate the back cover from the frame until it is completely removed
You can get step-by-step instructions for removing the back cover of a Samsung Galaxy on sites like iFixit and YouTube (if you can't find specific instructions for removing the back cover, search for Samsung Galaxy removal or battery replacement guide).
Is it easy to repair a Galaxy S21 smartphone?
PBKreviews concludes the video by giving the S21 a repairability score of 7.5 out of 10 . While you can't compare this result with iFixit's standardized and carefully designed assessment, it can be concluded that Samsung smartphones have at least become no more difficult to repair, and may even have become easier in this area.
For now, in order to understand maintainability on a more familiar scale, we need to wait a little longer. Let me remind you that last year’s Samsung flagship received only 3 points out of 10.
The most difficult thing to remove in almost any smartphone is the battery.
Removing the cover using improvised tools on the Samsung Galaxy S9
The more popular model Samsung Galaxy S9 is practically no different in the process of disassembling the case from other models. Here, too, the two components are glued together, as Samsung engineers decided. But we will consider manual disassembly of the device, without any special tools. We will use improvised means
, which are in every home. For example, instead of a hot air dryer, you can use a regular hair dryer to dry your hair. But use it to its full potential. Direct the hot air flow exclusively to the joints of the housing.
Use a hairdryer to heat the glued joints for several minutes. A suction cup is also required to safely remove the back cover.
Tools for opening the Samsung cover
It can be purchased at any children's store. Large suction cups are a priority - the more area of the back cover is covered, the stronger the suction cup will hold it. We will also need guitar picks (plastic plates in the shape of a triangle) or plastic cards. Use two to support the already opened parts of the body.
Procedure:
- Attach the suction cup to the top or bottom of your Samsung Galaxy S9. Little by little, begin to pull the cover away from the screen module. It's okay that she won't give in at first. Do this regularly, but without much effort. After some time, a gap will begin to appear between the body and the cover; Attach the suction cup to the back cover of Samsung
- Insert a plastic card or pick into it; Insert a pick or plastic card into the hole that appears.
- Gradually insert plastic objects into the new holes so that they do not stick together again; A mediator inserted into the hole between the cover and the Samsung body
- Move the pick further until the lid gradually peels off.
In this simple way you can easily open the back cover of almost any Samsung mobile phone.
Method 1 of 2: Samsung Galaxy S6 and S7
Remove the cover.
If your Samsung Galaxy smartphone is wearing a case, it must be removed before proceeding further.- Turn off the power to your smartphone.
Hold down the lock key and select
Shutdown
in the pop-up menu, and then confirm your choice.- If you remove the cover while the phone is turned on, there is a risk of short circuit or electric shock.
- Remove the SIM and SD cards.
This action is not necessary, but it is recommended to remove the cards so that they are not damaged by heat exposure.- Use a special accessory to remove the SIM card and insert the end into the special hole on the left on the top edge of the phone. Carefully remove the SIM and micro-SD card tray.
- Place your phone face down on a soft surface.
This precaution will protect the screen from scratches when removing the cover. - For example, you can place a towel or other soft pad under the screen.
- Apply heat to the back of your Samsung Galaxy.
The required duration of heat exposure is two minutes. It's best to use a hair dryer or blower, but don't heat one spot for more than a second. This procedure will warm up and loosen the adhesive that holds the back cover of the Samsung Galaxy smartphone to the inner frame of the device. [1] XSource of information- Point the blower at the back cover and quickly move up and down the surface in a zigzag motion to avoid damaging the smartphone.
You can also use a heating pad that can be heated in the microwave.
- Insert the split into the connecting seam on the body.
Where the top and back edges of the case meet, there is a small slot into which you can insert a spacer, flat-head screwdriver, credit card, or other flat object.
- It is necessary to separate the back cover from the front part, but do not pry off the entire cover at once.
7.Place the flat separator along the gap on either side of the smartphone.
For example, you can use a guitar pick or a credit card. The back cover should separate from the front of the device.
- Do not use metal parts to avoid damaging the phone from the inside.
8.Place the flat separator on the opposite side of the smartphone.
The back cover will then separate from the front of the case on both sides of the device.
- If necessary, reheat the glue.
9. Lift the back cover on the top edge and remove it from the device.
After this action, the entire back cover can be removed, since now it was held in place only by a strip of glue on the top edge.
- You can warm up the glue again and run the separator along the top edge to make the task easier.
- Place the back cover of your smartphone in a warm and dry place to avoid damaging the inside of the device when reinstalling the cover.
Method 2 of 2: Samsung Galaxy S – S5
- Remove the cover.
If your Samsung Galaxy smartphone is wearing a case, it must be removed before proceeding further.
- Turn off the power to your smartphone.
Hold down the lock key and select
Shutdown
in the pop-up menu, and then confirm your choice.- If you remove the cover while the phone is turned on, there is a risk of short circuit or electric shock.
- Place your phone face down on a soft surface.
This precaution will protect the screen from scratches when removing the cover. - Locate the slot to remove the back cover.
Depending on the phone model, this slot is located:- S4 and S5
– upper left corner of the back cover;
S2 and S3
– top edge of the back cover; - S4 and S5
- S
– bottom edge of the back cover. - Insert your fingernail into the slot.
You can also use a small flat-head screwdriver, guitar pick, or similar thin object. The main thing is to act carefully. - Carefully lift the back cover towards you.
It should separate from the phone body. - Remove the cover of the smartphone.

How to open the back panel on Samsung Galaxy S7 Edge
Let's look at an example of how specialists open the non-removable back covers on the Galaxy S7 Edge smartphone. It is much easier to do this when you have equipment special for this at hand. It resembles a regular vice, equipped with a large suction cup.
Device for opening the cover on a Samsung smartphone
It serves as a holding tool for the rear of the body. With this equipment you will not need a heat gun. Since it refers to methods that have a certain risk of breaking the Samsung with high temperature.
Procedure:
- In the middle there is a niche for the phone. The body is placed between two rubber vise holders;
- The lid of the device is closed and the suction cup is activated. It is attached to the back cover of a Samsung smartphone. The joints must be moistened with alcohol or an alcohol-containing solution;
Attaching a suction cup to the back cover of a Samsung smartphone - The pressure regulator, which is located on the right, comes into play. When twisting it, the smartphone body is held in a rubber vice, and the suction cup “pulls” upward;
Pressure regulator in the device - The regulator is hand-tightened, but not tightly tightened, since we are dealing with a fragile material. Every few minutes we tighten the regulator further.
Open case of a Samsung smartphone
Ultimately, the glue between the parts of the case gives way and the device is disassembled into two main parts - the back cover and the Samsung mobile phone module. When the cover comes off the module, there is no need to immediately open the device. It is necessary to remove the suction cup from the body, after which you can open the machine.
How a vacuum cleaner works: mechanics and electrical
The basis of any vacuum cleaner is the air pump (or fan). The engine is equipped with an impeller, which, while rotating, absorbs the air flow with blades and, after compression, sharply releases it out. The lines are located in the housing, as well as at the beginning and end of the air pump. Suction lines operate under low pressure, and pressure lines operate under high pressure. Air circulates in the housing, which is discharged during engine operation. Along with the air flow, dust particles are drawn into the hose with a nozzle and fall into the dust collection container. The dust settles there, and the air blows its small particles back out. In order to prevent the return of the smallest dust particles, modern models of vacuum cleaners are equipped with filters.
Important! Conventional vacuum cleaners (Samsung 1600 W and others) are intended for household use. They cannot be used to remove construction debris and dust from concrete.
The fan impeller is driven by a commutator-type electric motor. The alternating current indicator for such a mechanism is 220 V. Thyristor regulators are installed in high-power household units. With their help, you can limit the dust suction force and carry out gentle cleaning of the room. The electronic functions of the vacuum cleaner are controlled by a board located inside the housing.
How to remove the cover on a Samsung J5 phone
Recently, developers of mobile phones from different brands have begun to create cases in which the back cover is simply missing. In fact, it exists, but it is not possible for ordinary users to open it without special tools. For example, the two components of the Samsung J5 case are glued together. And in order to unstick them, the body must be subject to heating at a temperature of 100 degrees. This requires a hot air gun
.
Warming up the case with a hot air gun
Before opening the case, be sure to remove the slots for the SIM card and flash drive.
The barrel of the hot air gun should be aimed at the back of the Samsung and its seams. Then you need to arm yourself with a plastic card or a plastic scalpel to pry off the front screen module.
Use a plastic card to line the seams of the case
The cover is not a thin plastic sheet, as in classic smartphones, but rather a recess in the form of a bath. You should be very careful when working along the seam of the phone with a card. Don't run it too deep. 0.5 cm is quite enough. Be careful not to disrupt important phone modules.
Use a plastic card to open the Samsung case
When the lid gives way, do not rush to open the case completely; do it with caution. After all, both parts exchange information using a wide cable that connects the screen module and the Samsung motherboard.
Screen module cable in Samsung
To disconnect the cable, you need to open the fastening cover and remove the cable from the socket. It's quite simple. The main thing is not to rush and be careful.

Dry and wet cleaning of “internals” from dust
Often the cause of a suspicious hum of a vacuum cleaner and an unpleasant odor is the accumulation of dust inside it. It is better to remove dust using “dry” methods so as not to damage the fragile electronic filling and not to disrupt the function of the conductive paths on the board. A small soft brush is suitable for cleaning. You can also use a room fan. If dust and dirt cannot be removed “dry”, after moisture has entered, all parts must be dried as quickly as possible. Plastic elements can be washed under running water. They should be put back together only after they are completely dry.
The drum and cable are easy to dry clean, as is the plastic motor housing. If the casing cannot be cleaned without using water, make sure that it does not touch the electrical circuit. You can use another vacuum cleaner with a suitable attachment as a dry cleaning tool. This is exactly how dust is removed from motor collector plates and windings. Strong air pressure cleans the board and its small parts well – even with heavy dirt.
How to open the cover of SAMSUNG Galaxy A3
How it's done
It is important not to use brute force when disassembling a smartphone. Otherwise, this can lead to negative consequences: most likely the smartphone will not perform its functions.
Also, dents, scratches or other damage may appear on the device’s body, interfering with its normal operation and significantly spoiling its appearance.
Therefore, when disassembling the Samsung A3, strictly follow the instructions below.
- Find where your smartphone's speaker is located.
- You will see a small recess (slit) above the speaker (from the end). With its help the cover is removed.
- Do not lift the cover suddenly, otherwise you may damage the back panel. You can simply press it with your fingernail and gently pull it away from the device. There is no need to worry - it will not break. Do not use sharp objects under any circumstances!
The back cover is open!
How to open the cover of Samsung Galaxy A3 and Galaxy A3 mini
To open the lid, specialists, in addition to the above tools, use a specialized hair dryer to heat it up.
It is quite difficult to do such a procedure at home. After all, you will have to warm up the edges around the perimeter of the smartphone.
The phone is monolithic, so it is important to heat it at a temperature of no more than 150 degrees (use a regular hairdryer for this).
After heating, it is enough to carefully pry the cover with a sharpened plastic card, snapping the screen off the body. That's it - access to the internal modules is open!
If your goal is to completely disassemble the phone, then you need to carefully read the instructions for complete disassembly. Inserting the cover is also easy - follow the steps in the opposite order.
If you know any other methods on how to remove the cover from a Samsung Galaxy A3, share them in the comments. If you have any questions, ask, I will be happy to answer everything.
Xiaomi phones deservedly receive good reviews. In the production of any original Xiaomi phone, reliable components are used, which guarantees high quality products. But any equipment breaks down over time and requires repair. Therefore, there may be a need to disassemble telephone sets.
Of course, it is ideal that disassembly and subsequent repairs be carried out by specialists. This guarantees the quality of work and will allow you to have no doubt about the final result. But if you want to save on paying for their services, then you can learn how to remove the back cover on a Xiaomi Redmi phone or another model yourself.
We offer you a short instruction on how to open the back cover on a Xiaomi Redmi phone (including models 3 and 4), Mi Max, etc. Since almost all phones have the same design, this guide can be used for most mobile gadgets.
Sequencing
- First of all, we take out the SIM card tray. If you leave it in its original position inside the case, it will interfere when removing the cover.
- Direct disassembly starts with the procedure of opening the latches around the perimeter of the gadget. Opening the back cover is not so easy - you need to put in a lot of effort to cope with the task. But this must be done extremely carefully. The best and safest way to open the device is with a special spatula for working with phones. And certainly, in no case should you use sharp objects that can cause scratches when working with the back cover. You need to start opening the latches from one corner of the phone, gradually moving to the other.
- When the latches have yielded, slowly and carefully remove the back cover of the Xiaomi Redmi or Mi Max. Smoothly open the case and see a cable connecting the back surface to the touchscreen. Carefully remove the cable to disconnect the front panel.
- Now we have before us the “filling” of the Mi smartphone. Here we see the top panel with the installed chip, and the cameras there. The battery is located underneath them. Most often, the question of how to remove the back cover of Xiaomi Redmi or Mi Max appears when it is necessary to replace the cameras or battery. This is also relevant if the touchscreen is damaged, but without additional complex equipment you will definitely not be able to solve this problem at home.
- Although the insides of the smartphone are open to us, we cannot yet remove them. In addition to the cameras, we can get them if we open the seal, which can be easily pryed off with any flat object at hand.
- If you disassemble the phone to replace the battery or dig into the chip, you will have to work with a screwdriver. The internal elements are screwed to the lid with bolts. We unscrew them with a screwdriver, be sure to put them in a visible place so as not to lose them, and only after that we can continue disassembling them. Unscrewed bolts need to be given special attention - those that are attached from above are longer than those that are screwed from below. Therefore, put them in different places so as not to get confused.
- After unscrewing the bolts, open the protective panel on top, and a chip will appear in front of you. It is not recommended to make any changes to its configuration yourself.
- I close the back cover in the same way as I open it, but, of course, the steps are performed in reverse order. The main thing is to be careful and act carefully, and then everything will work out.
To get a more accurate idea of how to properly open a Mi Max phone and other Xiaomi models, we suggest you watch the training videos.
Apple products today are perhaps one of the most recognizable in the world. And the iPhone has long ceased to be just a smartphone with an apple logo on the back panel. It is a sign of taste and status and an indispensable attribute of a successful person. But, being a fragile thing, like most equipment, the iPhone is often damaged during active use.
Scratches, chips and abrasions spoil the appearance of the device, undermining the authority of its owner. Sometimes replacing the back cover becomes a necessary measure, but what if you don’t have time to visit a service center? This manipulation can be done at home, following simple instructions.

Mounting the back cover of a Samsung smartphone
The specificity of the Galaxy A50 is that the smartphone cannot be easily disassembled. This was done due to the peculiarities of the battery fastening: the battery here is not removable, but glued to the boards. To prevent users from carrying out independent repairs, the case is made conditionally non-separable.
Disassembling a smartphone is possible, but only with the use of special tools. Professionals who have already encountered the specifics of the model recommend dismantling part of the body according to the following algorithm:
- First, we prepare the necessary tools - a hair dryer, a suction cup, a thin plastic spatula or card, screwdrivers for small screws.
- Using a hairdryer at a low temperature, so as not to damage the holographic patterns, we begin to heat the back wall of the case.
- As soon as the plastic warms up enough, attach the suction cup to the part.
- Using a spatula or a thin plastic card, lightly pry up the gap between the parts and pull the suction cup.
The part has been removed, but we haven't gotten inside the phone yet. The perimeter of the case is fixed with screws, which must be unscrewed and the frame, protective screen, cables and then only the display module removed one by one.
If you need to replace the battery, you need to be careful not to damage the cables, remove them, and then move on to the connectors of the motherboard and fingerprint scanner. After installing a new battery or drying the parts, you should begin reassembling the Galaxy.
Why is it important how a smartphone is repaired?
Many users do not think about the importance of easy smartphone repair. They believe that the one-year warranty that is given upon purchase will cover all risks of use . The problem is that some damage is not covered by the warranty. For example, water getting inside the smartphone (even if it is protected from it), mechanical damage, damage associated with the use of non-original accessories, and some others.
What to buy instead of Samsung Galaxy S21. 6 best alternatives
When the warranty ends, the smartphone may still break. In this case, simple repairs will be even more relevant. The cost of a repair consists of the cost of the labor and the cost of the components that need to be replaced. If disassembly and assembly are simple, then repairs will be much cheaper .
Therefore, do not underestimate the importance of high repairability of a smartphone. Have you encountered any non-warranty repairs? Or maybe you did it yourself using video instructions published by iFixit and other sources?

The functions of smart watches are gradually becoming richer. They know how to monitor activity, give recommendations, monitor pulse and other parameters of the body. Just look, they will even learn to control blood sugar levels, and the functions of ECG and blood pressure measurement will surprise few people now. The problem is that there are very few watches with this feature. But now the time has come, and the most popular watch after the Apple Watch has the ability to monitor ECG and blood pressure in 31 countries at once. Let's figure out whether the function is available in Russia, how to enable it on the watch, and whether such measurements can be trusted.
If smart watches were once an outlandish toy for technology fans, now they have become a real must-have for everyone. There is no point in once again listing the advantages they provide. It’s enough to simply say that they have become like a gadget for people, and not like something incomprehensible on the wrist. Although most of them need to be charged about once every two days, this is not so bad if you use them constantly. On the contrary, it even disciplines in some way, like good classical “mechanics”. There is only one leader on the market and it has little to do with Android smartphones, but we are more interested in something else. I have already used the flagship Samsung Galaxy Watch more than once in different generations, and now I decided to pay more attention to the Samsung Galaxy Active 2. They are inexpensive, but, as it turns out, they provide a lot of possibilities. However, they also have enough disadvantages.
If you are even slightly interested in the topic of smartphones, then you probably know that Apple never makes discounts on iPhones. Unlike everyone else, who regularly organize promotions with gifts, pay more for trade-ins than they should, and simply reduce prices to completely indecent limits. Obviously, this is done to increase the attractiveness of the product. But is the popularity of Samsung smartphones not enough compared to the iPhone, or is Apple simply not interested in offering discounts to its customers? Let's try to figure it out.
How to close the lid back
It's even simpler here - you don't even need your nails. Take your smartphone and place it in a plastic case. Make sure that all elements, such as buttons and the camera, line up with the slots on the cover. Lightly press the phone against the body and walk around its entire perimeter in this way. You will hear characteristic clicks. Ready! Now you know how to open the cover of a BQ smartphone without damaging the case and screen. If something is not clear, watch the special training video.
The modern mobile phone was created to simplify our lives. In practice, however, difficulties may arise.
Thus, some device users note that not all phones are comfortable to use or are not as advanced as their predecessors.
Therefore, you will need this summary if you do not understand how to open the cover on the Samsung Galaxy A3.
It becomes so unpleasant when you don’t understand how to open the back cover, and as luck would have it, there is no one nearby who can give you a hint or help.
But everything is not so sad, and at the moment you will learn how, in this case, you need to properly handle the Samsung Galaxy A3.
Not an easy task for many
If you ask most users the question: “How to remove the cover on a Samsung A3?”, they will not be able to answer anything.
It seems that the development company decided that in order to perform such an act, we must contact phone service centers.
At the centers, specialists will do this simply and quickly. After all, for this they have a set of special tools: a “spatula” (a device that disconnects fasteners) and a Phillips screwdriver.
But what if you don’t have the ability to contact specialists or simply don’t have enough time to visit a service center? There is only one way out - to remove the back cover from the Galaxy A3 yourself.
How to fix minor damage
In case of minor breakdowns, you can try to repair the Samsung vacuum cleaner yourself. Sometimes it makes an excessively loud noise or vibrates. Most often this happens due to the following reasons:
A diagram for disassembling the vacuum cleaner is presented in the instructions for its use. Emptying the dust bag is the easiest way, especially if it is disposable. In the instructions you can always find diagrams and tips that may be useful. If you don’t have the skills to repair household appliances, it’s not easy to understand the circuits, but if you have experience, it’s worth a try.
Most often people encounter the following problems:
Loss of power: what is the reason
When the suction power of a Samsung vacuum cleaner drops, most of the dust and small debris remain on the floor. If this happens, check the tightness of the pipe, brush and corrugated hose. You need to disconnect the corrugation, remove the tube and nozzle and carefully inspect all the elements. Turn on the unit, blow out the pipe with the hose: perhaps a piece of paper or some other object has gotten inside. If the item is detected and removed, all that remains is to reassemble the vacuum cleaner, plug it back in and continue cleaning.
Weak traction can occur as a result of a hair or fur ball wrapping around the brush. After removing the lump, the operation of the vacuum cleaner is restored. Since any attachment is curved, debris can get stuck in the curved area. You need to proceed like this: carefully disassemble the brush, unscrewing the fasteners, then remove the foreign object from the bend and put the brush back together.
Before you start disassembling the vacuum cleaner, you need to check what power its regulator is set to. Maybe you accidentally touched the lever while moving the device around the apartment. If it turns out that the lever is at the minimum, adjust it and continue cleaning.
What to do if the filters are clogged
When the filters become clogged, the Samsung vacuum cleaner also pulls weakly and makes uncharacteristic sounds. Severe clogging of the filter system can be accompanied by a complete stop of its operation. First of all, you need to clean the cyclone filter, which is made of transparent plastic. As a rule, it has several compartments. There is a sponge in the container that also needs cleaning. In some cases, it is necessary to completely replace the filters and equip the engine with an additional protection system.
When to disassemble a Samsung smartphone
Disassembling the gadget may be required in the following situations:
- A small amount of water gets on the surface of the device. In this case, it is better to disassemble the device and make sure that no liquid gets inside.
Important! If the phone falls into a container of water, disassemble it and remove the battery. Then take the phone to a service center as quickly as possible. Do not unplug the modules and try to dry them with a hairdryer.
- The need to replace the SIM card or battery.
- Inserting or removing a memory card.
- Checking the board for faults after the device falls. Some problems, for example, a cable that turns off due to an impact, can be easily fixed at home.
How much does it cost to replace a screen?
With the cost of work, everything is simple; inexpensive service centers charge an average of 1000-2000 rubles for glass replacement for most phone models. The price may be higher if it is very difficult to change the glass for a particular phone model.
- • Install the suction cup on the bottom area of the cover.
- • Pull it and insert a guitar pick into the gap (just don’t go too far).
- • Remove the suction cup and pull the cap.
- • Add more mediators to fix the gap and, using sliding movements of one of them, separate the remaining sections of the cover.
- • Remove the cover completely.
