Introduction

Use this guide to replace a cracked or broken screen on your Samsung Galaxy A51.

Note: The function of the fingerprint sensor might be lost after this screen replacement. Security patches installed after September 2020 don’t support this repair.

If the frame is deformed, it's important to replace it to make sure the new screen will mount correctly and won’t suffer damage from uneven pressure.

Before disassembling your phone, discharge the battery below 25%. The battery can catch fire and/or explode if accidentally punctured, but the chances of that happening are much lower if discharged.

This guide instructs you to replace the screen while leaving the original frame and motherboard in place. However, some replacement screens for this phone come pre-installed in a new frame (a.k.a. chassis), which requires a very different procedure. Make sure you have the correct part before starting this guide.

You’ll need replacement adhesive to reattach components when reassembling the device.

Galaxy A51 Screen

Step 1

Insert a SIM card eject tool, a SIM eject bit or a straightened paper clip into the hole on the SIM tray located at the left side of the phone.
Press firmly to eject the tray.
Remove the SIM card tray.
When reinserting the cards, make sure to properly orient them in the tray.

Kijk uit voor de vingerafdruk scanner. Er zit een kleine flat cable aan die kapot gaat als je de behuizing er in 1 keer vanaf haalt

Falls der vorherigen Kommentar nicht verstanden wird, hier nun die Übersetzung 😉 Achte dabei auf den Fingerprint Scanner, da ist ein kleines flaches Kabel dran welches kaputt geht wenn Du die Hülle auf einmal entfernst.... also Vorsicht ist hier wohl geboten, wenn man sich an dieses scheinbar Einfache heran macht.

Step 2

Before beginning this procedure, completely power off your phone.
Prepare an iOpener and apply it to the back cover to soften the adhesive.
The adhesive of the Samsung Galaxy A51 is very strong. You can use a hair dryer or a heat gun if you aren't able to open the device with the iOpener.
Be careful not to overheat the phone—the AMOLED display and internal battery are both susceptible to heat damage.

Step 3

Insert the tip of an opening pick between the frame and the back cover at the bottom of the phone near the USB-C port.
If you can't get between the back cover and midframe with your opening pick, you can use a suction handle or strong tape to pull up the back cover to create a gap.
Slide the opening pick to the bottom right corner and leave it there.

Step 4

Insert a second opening pick and slide it from the bottom right corner to the bottom left corner to cut the adhesive.
Leave the opening picks in place to prevent the adhesive from resealing.

Step 5

Insert a third opening pick under the bottom left corner of the back cover.
If you have any trouble, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.
Slide the opening pick along the left edge of the phone.
Leave the opening pick in the top left corner to prevent the adhesive from resealing.

Step 6

Insert a fourth opening pick under the top left corner of the back cover near the camera.
Slide the tip of the opening pick along the top edge of the phone to the right corner to cut the adhesive.
Leave the opening pick in the top right corner to prevent the adhesive from resealing.

Step 7

With opening picks in all four corners, insert a fifth and final opening pick under the top right corner of the back cover.
Slide the tip of the opening pick along the right edge of the phone to the bottom right corner to cut the remaining adhesive.

Step 8

Remove the back cover.
After installing the back cover, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond—a stack of heavy books works well.

Step 9

Remove the thirteen 3 mm Phillips #00 screws securing the midframe.

Step 10

The midframe is held in place by plastic clips.
Insert an opening pick between the midframe and front panel assembly on the bottom of the phone near the charge port.
Slide the opening pick to the left bottom corner to release the plastic clips.
Slide the opening pick to the bottom right corner to release the rest of the bottom plastic clips.

Step 11

Continue sliding the opening pick on the right side of your phone until all plastic clips on the right side are released.

Step 12

Slide the opening pick along the top edge to release the top plastic clips.

Step 13

Slide the opening pick from the top left corner to the bottom left corner to release the left side's plastic clips.

Step 14

Remove the midframe.

Step 15

Use the flat end of a spudger to disconnect the battery by prying the connector straight up from its socket.

Step 16

Use the flat end of a spudger to pry up and disconnect the display flex cable on the bottom of the phone.

Step 17

Prepare an iOpener and apply it to the display for at least two minutes to loosen the adhesive beneath.
You may need to reheat and reapply the iOpener several times to get the phone warm enough to cut the adhesive. Follow the iOpener instructions to avoid overheating.

Step 18

Once the screen is warm to the touch, apply a suction cup to the upper edge of the phone.
If the screen is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed.
Insert an opening pick in the gap and start to cut the adhesive by sliding it to the top right corner.

Step 19

Insert a second opening pick and slide it to the top left corner.
Leave the opening picks in place to prevent the adhesive from resealing.

Step 20

Insert a third opening pick and slide it along the left edge to cut the adhesive.
Leave the opening pick in the bottom left corner to prevent the adhesive from resealing.

Step 21

Insert a fourth opening pick and slide it from the bottom left corner to the bottom right corner.
Leave the opening pick in its place to prevent the adhesive from resealing.

Step 22

Insert a fifth opening pick and slide it along the left edge of the phone to cut the remaining adhesive.

Step 23

Reapply a heated iOpener to the screen to loosen the adhesive underneath.
As you wait, take note of the rectangular-shaped adhesive placed underneath the screen.

Que voulez-vous dire pare prenez note du rectangle d'adhésif en dessous de l'écran

Patrick Gargowitsch -

Bonjour @patrickgar51601 c'est l'adhésif qui fixe l'écran, entouré en rouge sur la seconde photo de l'étape, et que vous devez décoller pendant l'étape suivante. Il est important de visualiser son emplacement pour mener à bien la procédure.

Claire Miesch -

Step 24

Insert a plastic card on the left edge into the gap between display and the phone assembly.
Press the plastic card in and slide it back and forth until you cut through the entire adhesive.
Once you are sure you cut through the adhesive, remove the four opening picks from the corners.
Do not remove the screen completely yet. The display cable is still threaded through the frame.

Bonjour, dans mon cas, la vitre teintée s’est décollée du Oled. J’ai ensuite chauffé et soulevé l’écran Oled (surface argentée) qui se brise en centaine d’éclats (attention les yeux). Le dessous de l’écran Oled est couvert d’un film de cuivre.

Step 25

Carefully thread the display cable through the frame.

Step 26

Remove the screen.

Conclusion

If possible, turn on your device and test your repair before installing new adhesive and resealing.

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow these instructions in reverse order. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

The best way to secure the new screen is to apply a sheet of custom-cut double-sided tape to the back of the screen.

Take your e-waste to an R2 or e-Stewards certified recycler.

Fingerprint scanner is disabled when original screen is replaced

You need to buy the right replacement screen like the one that supports fingerprint like amoled

Attention, Fingerprint makes some trouble after replaceing the display

Fernseh Hartung - 16/02/21

I see that users have posted about the Fingerprint Scanner causing issues. “…disabled when original screen is replaced” or “… some trouble after replacing…” Are these issues that since have been resolved? Scanner can be re-enabled or disabled and re-enabled to bypass the “issues”?

Hi, as far as we know, there is no official solution for this issue yet. We hope Samsung fixes this issue or provides a way for 3rd party repair technicians to calibrate new sensors. If you want to know more about this topic you can watch this video from Hugh Jeffreys: https://www.youtube.com/watch?v=zGLQ9ZRn....

If you find any other news about this topic share it with us. :)

So I ordered the replacement Digitizer and Screen for my A51 but I didn’t pay attention and it didn’t come with everything assemble to the frame. Most of the videos show their replacements coming in and all they are having to do is move all the hardware from the broken screen/digitizer to the replacement. I wanted to verify that this guide is allowing me to use the old frame before I re-purchase new replacement parts. I understand the photos show the screen and digitizer being removed from the frame.

Hi, these guide describe how to replace the screen while leaving the original frame and motherboard in place. Good luck with the repair!

After replacing the screen and close the phone the louder speaker not working, what maybe the cause?

jecky de beer -

So, while having difficulty getting the adhesive to release, my plastic tools would not get under the glass…. Using a hobby knife was not a wise choice. I tore the antenna on the back near the USB-C port. Any info on what antenna I harmed, and potentially a source? Foil looks like it is on some type of Kapton tape, which I think I *might* be able to bridge, but that increased the difficulty by an order of magnitude (Trace repair is easier with access to a 40x Stereoscope).

The antenna opposite to the camera was torn and remained partly stuck to the back !

A WARNING about this issue is missing ! It could be a mistake with the mediator, or a too low temperature at this location, or just bad luck...

Then it is impossible to push the ifixit mediator at the level of the usb port. This mediator is too thick ! It worked near the sdcard slot.

The procedure to remove the screen is not valid when you have a block screen part.

Moreover, the gluing of the back does not seem so easy. We need to clean...

Conclusion it is very fragile and delicate.
