Samsung Galaxy A70 2019 (A705): how to disassemble and replace the display

It so happens with Samsung smartphones that if you bring them for repair, most often to replace the display module. Bright and saturated AMOLED displays, no matter how cool they are from year to year, remain fragile. One hard fall completely wipes out the “picture”.

Today’s A70 was no exception. Drops on the corner are some of the most dangerous. Glass is almost always cracked, often the matrix is damaged because it is weakest in the corner areas.

Let’s start with removing the SIM card tray. Paper clip, needle or thin screwdriver. the main thing is not fanaticism. The mechanism of removing the tray is not the strongest one.

I have left the process of back cover detaching out of the picture, as it is very simple. Made of plastic cover is much stronger and more flexible than a glass cover, it can be peeled off with a normal disassembly spatula. We create the necessary gap and, using the tool as a wedge, peel the cover off. Also do not bend the cover too much, you might notice some bending marks.

The whole set of screws holds the back frame, hiding from us phone insides. Unscrew it methodically and put it aside. The screws are the same, you don’t have to worry about mixing them up.

We use the same spatula to unclip the back frame from the case and set it aside. As you can see, the frame still has the contacts of the volume and power buttons, as well as the external speaker and the wireless charger.

After you got access to the board you disconnect the battery. Removing the risk of accidental shorting in the process of disassembly.

It’s a good time to check the new display module before installation. I always do this, it is better to spend a small amount of time than to install a defective part without the possibility of exchange or refund.

Structurally it’s very simple: disconnect the connector of the old display (on the lower sub-board) and connect the new one.

Since all the buttons and cable stayed on the back frame, let’s replace them by simple shorting of the flexible contacts. I’ve marked the pins I need. Any instrument made of conductive material will do. Press both pins for a couple of seconds and voila: we see the Samsung inscription.

After starting the system set the maximum brightness and meticulously inspect the picture. On a light background, on a dark background, in all corners. Make sure that there are no graphic distortions and artifacts.

The sensor can be checked by dragging icons, typing the keyboard, pulling the shutters and scrolling through lists.

Since we have a new display module with a frame, all we need is to transfer the internal components to a new base.

All peripherals should be unplugged, also take out the main board and the bottom additional board.

There are inscriptions on the board-to-board cable that will help you not to mix up the ends. “MAIN” should be connected to the main board and “SUB” to the bottom board.

Raising the main board we do not hurry to put it on a new frame: there are still a vibration motor and a speaker under the board.

Unscrew the 2 screws of the fingerprint scanner and set aside for now.

Lift the lower board. It is slightly glued to the base, so if you have difficulties it is better to pour alcohol or heat.

We start the transfer with three components: the speaking speaker, the vibration motor and the antenna cable. Lift everything with tweezers and transfer to the appropriate places.

On this model the battery is glued quite firmly and over a wide area, there are no tags to pull it out. I share a simple method: I pour a small amount of alcohol into the specified places and leave it for a minute. The alcohol will loosen the double sided adhesive tape and the battery can be removed with your bare fingers.

In this picture you can clearly see the factory sealing of the battery. Before replacing the battery clean the old adhesive tape from the battery.

During the last inspection of the disassembled frame I noticed an interesting thing. On the inside of the window for the fingerprint scanner you can clearly see the display matrix crack.

Put two strips of double sided tape on the new frame for the battery and peel off all protective and shipping films.

Reassemble the device in the reverse order but do not put the lid on. Do one last test and only then put the plastic panel back in place.

I managed to peel the cover without damaging the original adhesive so I just put it back on. If you have removed or damaged the tape, the best choice would be to glue the cover back on (B-7000, T-7000, E-8000, etc.д.).

How to replace the display on the Samsung A70

Most of the current flagship smartphones are equipped with Samsung branded OLED displays, offering the user high contrast, brightness and color saturation, even in direct sunlight.

The display panel is thin and takes minimum space, due to which smartphones rest perfectly in the hand and do not weigh like a “brick. However, there is a downside of such technology. fragility.

For the user of the phone, a fall can result in the complete loss of image, but the cause remains undetected. It will take some effort and experience to see the crack on the display matrix, as in the example above. Such a part can not be restored, which means that the screen on the Samsung A70 will change completely.

We have the original service part complete with the frame and all the necessary sealant and thermal rubber bands to replace it. All we have to do is to disassemble the phone and transfer all the internal components and the back cover to the new frame.

Start with the back cover. Here it is made of plastic and, by and large, there should be no problems to remove it. For convenience and speed, you can slightly heat the back part.

To remove it we use a pair: thin film isopropyl alcohol. A laminated card will also do, the main thing is thinner.

The mechanics are simple: put the tape in the gap, wet it with a little alcohol, slowly and gently run it along all the edges and peel the tape off the frame. As soon as it is difficult to move the film, we add alcohol.

As you can see on the picture, there is more tape on the bottom part, you will need to put the tape “up”. Avoid excessive bending and twisting of the back cover, the plastic is flexible, but the color layer can be damaged.

The next step is to separate the plastic frame. It is only held in place by screws. We unscrew the specified screws and remove the SIM-card tray. The screws are the same length so you can’t mix them up.

Use a flat disassembly tool or a plastic pick and loosen the frame from its catches. The external speaker remains on the inside of the frame, as well as the outputs of the volume and power buttons.

Let’s begin to move the components. Disconnect the battery, antenna cable and inter-board cable from the main board.

On the lower sub-board we need to disconnect the fingerprint scanner unit, the other end of the interboard stub, the display connector and the antenna cable.

Don’t hurry to move the board right away: underneath it there is the speaking speaker and the vibration motor.

Lift the speaking speaker and the vibration motor. A fine set of tweezers will do the job.

The loop is double sided. MAIN” and the arrow up will prevent mixing up the ends. this end is connected to the main board.

Fingerprint scanner. It is better not to contaminate its lens.

When reassembling the antenna cable we put it in the same channel of the case as during disassembly.

The bottom sub-board is glued to the case with an adhesive base. The best thing to do is to gently pry it up with the tweezers so as not to damage the components on the back side.

With this model the battery is glued to the base very firmly. It’s easy to disassemble if you have isopropyl alcohol on hand. We add a small amount to the sides and bottom, so that it runs under the battery. After a couple of minutes the battery will come off without much effort.

With a new display module remove all protective and shipping films, install the speaker, vibration motor and assemble the unit in reverse order.

Install the battery in its new place with double-sided acrylic adhesive tape.

We use alcohol during disassembling, so the factory glue base on the back cover is still in perfect condition, so you can put it back. If the factory adhesive tape was damaged during disassembly, it must be replaced by an adhesive such as B-7000.
