Opening the device case may be necessary in different situations. Replacing the battery yourself, checking the functionality of the gadget if water gets in – this is not a complete list of possible situations. Some phones cannot be disassembled with ordinary tools, and most manufacturers will refuse warranty service if they discover that the smartphone has been disassembled by the buyer. In this article we will tell you how to disassemble a Samsung phone if you decide to take this step.
Important! Opening the device may void the warranty. This is especially true for models with a non-removable battery. This instruction is not a call to action.
Procedure for disassembling a Samsung smartphone
The disassembly instructions are suitable for most models of the Korean giant, but the location and number of screws, connectors and latches differ in different devices.
- Let's start by removing the back cover. If this item is only attached to your Samsung device by a latch, carefully lift the cover and remove it from the clips. This mounting method is often found on older models. For the entire Galaxy line, carefully slide the pick or card between the cover and the body where it is easiest to do so. Now slide the card around the perimeter of the smartphone, carefully releasing the latches. Once all fasteners are unlocked, remove the cover.
- If the purpose of the procedure is to check the presence of water in the device, you can begin the inspection now. Check for fluid and oxidation on the battery and around the camera module.
- Now you can remove the battery. Carefully lift it up and remove it from its slot. The humidity sensor is usually 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 If its color is not white, water has entered the smartphone and the warranty is no longer valid.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 gap between these elements and sliding it around the perimeter of the device.
- Remove the metal heat spreader plate from the cooktop, if equipped. To do this, unscrew the fixing screws and pry them 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 chip, just remove them from the end of the case.
- Let's start disassembling the board itself. Carefully remove all screws used to secure it. Their number varies on different smartphones and tablets. After unscrewing the screws, carefully release the microcircuit from the case, but do not remove it!
- Using a flat-head screwdriver or a bat, pry off the board and disconnect the display cable from the connector. Disconnect the remaining cables: speaker, microphone, and connectors.
- Pull out the board and set it aside.
At this point, the main stage of disassembly can be considered complete. If necessary, visually inspect the modules.
When disassembling, always put small screws in a small container, otherwise they are easy to lose.
Disassembling display elements is a much more difficult task. Screen mounts can vary greatly between devices, so it's best to leave this task to a professional. Do not try to replace the screen “at home” without the necessary skills; such a procedure can end sadly for your device.
Preparation
Disassembling a washing machine is not difficult if the owner of the device has minimal skills in electrical engineering and plumbing. In Samsung brand models, such as, for example, S821, WF-S861, S803J, WF6458N7W, it is easy to access the main mechanisms.
To disassemble and subsequently repair the washing machine, you need to choose a bright and spacious place where nothing will interfere with the work.
Whatever machine you are going to repair, first it is important to prepare a workplace and tools that will be useful during the disassembly process. Of course, you can get started with a few screwdrivers and wrenches. But if the machine requires a detailed inspection and subsequent repairs, it is better to prepare everything you need at once. So, you may need:
- hammer;
- wire cutters;
- screwdrivers (slotted and figured);
- open-end wrenches;
- heads (socket wrenches);
- pliers;
- hacksaw;
- pliers;
- mites;
- soldering iron
It is important to prepare auxiliary materials in advance - liquid for softening nut fasteners WD-40, silicone sealant and lubricant for hinge elements. It is convenient to have a clean rag on hand to wipe your hands or any remaining liquid from the machine. Experienced craftsmen advise beginners to photograph each stage of disassembling the unit to make it easier to reassemble the device after completion of the repair, therefore, you need to prepare a camera.

The preparation stage may not seem so important, but the result largely depends on the quality of its implementation.

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.
Removing the cover using improvised tools on the Samsung Galaxy S9
The most popular model, the Samsung Galaxy S9, is practically no different from other models in terms of disassembling the case. Here, too, two components are glued together, as Samsung engineers decided. But we will consider manual disassembly of the device, without special tools. Let's use available tools that are found in every home. For example, instead of using a heat gun, you can dry your hair with a regular hairdryer. But use it to the fullest. Direct the flow of hot air exclusively towards the box gaskets.
The glued joints must be heated with a hairdryer for several minutes. A suction cup is also needed to safely remove the back cover.
Samsung Cover Opening Tools
It can be bought at any children's store. Large suction cups are a priority - the larger the area of the back cover, the stronger the suction cup will hold it. We will also need guitar picks (triangular plastic plates) or plastic cards. Use two to support already exposed parts of the body.
Procedure:
- Attach the suction cup to the top or bottom of your Samsung Galaxy S9. Gradually begin to remove the display module cover. There is nothing that 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 lid;
Attach the suction cup to the Samsung back cover - Insert a plastic card or pick into it;
Insert a pickaxe or plastic card into the hole that appears. - Gradually insert the plastic objects into the new holes to prevent them from sticking together again;
The master key is inserted into the hole between the cover and the Samsung body - Push the spout further forward to gradually remove the cap.
In this simple way, you can easily open the back cover of almost any Samsung mobile phone.

How to remove the cover on a Samsung J5 phone
Recently, developers of mobile phones of various brands have begun to create cases that simply do not have a back cover. This is true, but ordinary users cannot open it without special tools. For example, two components of the Samsung J5 case are glued together. And in order to glue them together, the shell must be heated to a temperature of 100 degrees. For this you will need a heat gun.
Heating the case with a heat gun
Before opening the case, be sure to remove the SIM card cells and the flash drive.
The barrel of the hair dryer 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 pull out the front display module.
Use plastic card to lift body seams
The cover is not a thin plastic sheet, as in classic smartphones, but a bathtub-shaped hole. You need to work very carefully along the seam between the phone and the card. Don't go too deep. 0.5 cm is enough. Be careful not to damage important phone modules.
Use a plastic card to open the Samsung case
When the lid gives way, do not rush to open the box completely, do it with caution. After all, both parties exchange information using a wide cable connecting the display module and the Samsung motherboard.
Samsung Display Module Cable
To disconnect the cable, you must open the retaining cover and remove the cable from the socket. It's quite simple. The main thing is to take your time and be careful.
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.

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.
