How to remove the back cover of Samsung S6. How to replace the back cover of Samsung Galaxy S6 Edge
Let's find out in what ways you can open the back cover of your Samsung mobile phone. No mobile phone is complete without a SIM card. This is a small chip that provides us with cellular communication services. On some Samsung models, you need to remove the panel to gain access to the cell where the chip is inserted. And also Micro-SD - flash drive for a mobile device. Or get to the motherboard for repair.
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 will require 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.

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.
How to open the back panel on Samsung Galaxy S7 Edge
Let's look at an example of how to open non-removable back covers specialists 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;

- 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;

- 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.

Ultimately, the glue between the parts of the case gives way and the device is disassembled into two main parts - the back cover and 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.
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. Larger suction cups are preferred - 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:
Hello dear readers. Today, together with you, we will learn how to disassemble the Samsung Galaxy S6 on our own, without the help of a specialist. Since this model of the Korean smartphone does not have a removable back cover, at first glance it may seem that disassembling it is not so easy. However, with us you can do anything!
It is important to understand that the initiative to disassemble the Samsung S6 yourself will deprive you of warranty service. Therefore, before disassembling it, weigh the pros and cons.
So, get ready for the fact that when you remove the back panel, you will see a copious amount of glue along its edges, this is one of the distinctive features of Korean manufacturers. By the way, since disassembling a Samsung Galaxy S6 is no different from disassembling a regular Galaxy S6, we will demonstrate the entire process on it.
Most often, the Samsung S6 needs to be disassembled to change the battery, due to its problematic availability. To do this, you need to use plastic tools so as not to damage the insides of the Galaxy S6; a common example is an ordinary plastic card.
Experienced craftsmen have in their arsenal various tricks for disassembling smart phones; we recommend prying off the back cover with the same credit card. The cover will give in easier if you pre-heat the phone on its side with a stream of warm air, so the glue will melt a little.
First step This very white film around the edges is glue, as they said, there is plenty of it here.
Second step Smoothly, without sudden movements, remove the back panel.
Third step
The S6 Edge's screen and metal body sit well on small screws that need to be removed with a small Phillips screwdriver. Then, when there are no more screws holding the screen in place, it can be removed from the case.
Fourth step As we can see, the motherboard is not attached to the Galaxy S6 body, but to its screen. Therefore, we remove it only after disconnecting the antenna wires.
Fifth step Now we can remove the Galaxy S6 battery when the L-shaped board has already been removed and we have free access to the battery.
Sixth step Now we can remove the fingerprint scanner.
Seventh step Now you can remove the glass from the smart screen, but before doing this, it is also advisable to warm it up with a hairdryer.

Opening up the S9+
In order to safely disassemble the S9+, follow the recommendations below (remember that you carry out repairs to the device at your own responsibility).
Heating with a hairdryer (you can use a separator), lift the frame and separate the upper and lower parts to the sides.
Attention: the case must be opened carefully, without using excessive force.
S9+ disassembly
We divide the smartphone into two parts.
We remove the fingerprint sensor. An adhesive edge holds it to the lid. We use liquid to separate it.
The fingerprint sensor cable is also glued. Therefore, when you open the lid, there is a risk of damaging it.
Once you unscrew the fifteen screws, the familiar two-piece plate in the middle of the case will pop out with a built-in wireless charging coil, antenna assembly, and bottom-mounted speaker on board.
Removing the battery
What do you need to remove a stuck battery from a Galaxy phone?
- heat up a little
- a syringe with a small amount of liquid to remove glue
We take and add some liquid to the small recess that holds the battery. After a few minutes the battery separates.
Removing the motherboard
Unscrew the two screws and disconnect the pair of FPCM connectors securing the motherboard.
The display cable is passed through a slot in the case and snapped onto the motherboard. Be careful.
Carefully remove the S9+ board from the phone body.
We shoot the periphery
The dual camera is a single device on one circuit board with one connector and is easily detachable.
The total number of cameras on the S9+ is now four – in addition to the (recently removed) dual main camera, we have a selfie camera and aperture cameras.
Disassembling the components of the back cover
The headphone jack is equipped with a sealing gasket to protect the phone from moisture. And the modularity makes it easy to remove if replacement is necessary.
We hook up and separate the multi-purpose daughter board assembly with coaxial connecting cables, microphone, USB-C connector and spring contacts.
Motherboard Components: Side A
Side A contains:
- Samsung K3UH6H6-NGCJ LPDDR4X 6 GB DRAM RAM chip layered on top of Qualcomm Snapdragon 845

Samsung's screen cable, like the cameras, is Star marked and combines the display and digitizer into one sealed device.
On the right is hardware support similar to Face ID, including a front-facing camera, an infrared dot projector, an infrared camera, and space for a flashlight and distance sensor built into the display.
Conclusion
After reading this article, you will get an idea of the process of disassembling a Samsung Galaxy S9+ phone and its constituent components.
We remind you that in our bgacenter training center, you can learn the principles of diagnosing and repairing mobile phones. And also gain practical skills in soldering bga chips. Which will allow you to earn good money, friends.
Detailed photo instructions: how to disassemble the Samsung Galaxy S6 Edge + review and full specifications of the Samsung Galaxy S6 Edge smartphone.
Samsung's flagship, with a curved screen on both sides.
At the bottom of the phone there is a speaker, microphone, headphone jack and USB 2.0 port.
At the top end of the phone there is a second microphone, an IR transmitter and a SIM card tray.
So, to remove the back cover we need a pick and a suction cup. Gone are the days when the back cover could be removed by simply sliding it.
The back cover fits very tightly to the body and removing it is not so easy, but it is possible.
After you separate the back cover from the phone body, clean everything from the glue.
Interestingly, the battery is not located in the body of the phone, but on the front along with the display module. There are no components at all on the middle part of the phone body.
Let's separate the two halves of our phone using a screwdriver.
After unscrewing all the screws, take a plastic spatula and separate the case into two parts.
As you can see from the photo below, we still cannot remove the battery; to do this we will have to remove the motherboard.
According to Samsung, the antennas are ultrasonic welded to save space.
The power button is also soldered to the body using ultrasonic welding and we cannot remove it.
So, at this stage we can remove the motherboard by first disconnecting the two coaxial cables.
Now you can remove the main camera from the motherboard.
This is what the main rear and front cameras look like. The main camera has a dual-axis gyro chip for optical image stabilization (in the yellow square) and a serial flash memory chip (in the red square).
Finally we can remove the battery, which is held in place by a strip of glue.
Remove the board with the USB 2.0 port from the case. Why Samsung decided to install 2.0 and not 3.0 is a big mystery to us. Perhaps to save space, but losing 90% of productivity because of this is absurd. Hello from 2000)))
The biggest problem with the Samsung Galaxy S6 Edge is replacing the display, as removing it has a high chance of damaging it. But if you still want to remove it, you can take a risk, and maybe it will work out. According to Samsung, the curved glass is created using a process called 3D thermoforming, a process of heating and shaping the curved glass, which makes it up to eight times more expensive to make. Judge for yourself: regular glass costs about $3, and curved glass costs about $25.
We remove the glass and... we see an unusual curved AMOLED display. By the way, it is precisely because of this display that some users see bubbles, pimples, stripes and other strange formations under the protective glass))). Samsung admitted that this is a flaw and phones with such a defect must be replaced.
The last component that can be removed from the display frame is the Home button along with the fingerprint sensor.
So we took apart the Samsung Galaxy S6 Edge. Below is a photo of all the components that we managed to remove.

In the new generation of Galaxy S6 smartphones, Samsung has completely revised the concept of a phone device. They made smartphones similar to iPhones both outside and inside. Therefore, it will be especially interesting to learn how to disassemble the Samsung Galaxy S6 Edge, which breaks as easily as the iPhone 6. During the disassembly process, you can learn how to replace the back glass and display of the Samsung Galaxy S6. Samsung wouldn't be an Asian company if it made a smartphone without glue. The first thing you have to prepare for is a copious amount of glue in the structure. To remove the back cover of the Samsung Galaxy S6 Edge, you need to warm it up around the perimeter, then press the edge with a suction cup or slip a pick and walk along the entire device.
The back cover of the Samsung Galaxy S6 and Samsung Galaxy S6 Edge is purely decorative. Hidden underneath are the screws that make the frame, display, and motherboard into a single device. Therefore, you remove the cover to the side and continue to disassemble the smartphone with a screwdriver.
The display panel and aluminum frame of the Samsung Galaxy S6 Edge are held together with 13 screws, which can be removed with a Phillips screwdriver. Once the screws are unscrewed, the display can be picked up with a spatula and removed from the grooves of the frame. The smartphone will split into two halves. The aluminum frame is a strength frame and an antenna at the same time.
Samsung has once again made a device in which the main elements are attached to the display module, and not to the supporting aluminum frame. This is a strange approach, time will tell how justified it is and how it affects the survivability of the Galaxy S6 Edge. Next, you should remove the motherboard by disconnecting the two coaxial antenna conductors.
The battery connector is hidden under the motherboard. To use Edge, you will need to completely disassemble the smartphone and remove the motherboard. Miracles in a sieve. The battery tends to become outdated during use, while the flagship model on the market will be relevant. In a year or two, Samsung Galaxy S6 owners will face headaches and the high cost of typical repairs.
Samsung made their own version of Touch ID, which, unlike the iPhone, can be replaced, which is a good sign.
The curved glass of the Samsung Galaxy S6 Edge is separated from the display by heat. After the Edge falls, a curved display will be possible if the latter is not damaged.
