22 steps

Remove the back cover
The first step is to loosen the heavily glued backcover. To loosen the back cover, the edge of the unit should be heated with hot air. A temperature of about 60 to 80 degrees is recommended. It should still be possible to touch the device with bare fingers without it being too hot.

When the adhesive is heated, place a suction cup at the bottom of the back cover. Slowly pull on the suction cup while pushing your opening tool such as the iFlex or iPlastix into the gap that is opening between the backcover and the frame.

You can also use an iSclack to help lift the back cover a little. The iSclack has suction cups on two sides to pull the display and back cover evenly.

The iFlex is made of thin yet stable metal and is therefore easier to insert into the narrow gap. However, it is also easier to scratch the back glass or the frame of the device with this tool.The iPlastix is made of plastic, slightly more flexible than the iFlex and therefore a little more difficult to insert into the gap. The iFlex can be used initially to get into the gap at first. After that, you can continue working with the plastic tool.

Once the tool is inserted, slide it along the edge of the frame. Then gradually place a flat plectrum into the already detached part. This will prevent the glue from rejoining at these points.

At the left edge of the back cover you should be careful not to insert your tool too far into the device. There is a flex cable running along, which could otherwise be easily damaged. In the upper part of the back cover you should be careful not to scratch along the camera module. The backcover is very heavily glued in this area.
The back cover is made of glass and can therefore break easily. Take enough time for this step and work carefully. Also warm up the frame from time to time. It can take 30 minutes to loosen such a strongly glued backcover.
Remove the main board cover
6 × 3,3 mm Phillips

The NFC antenna is also located on the cover of the main board.
To remove the main board cover, the camera must first be extended.
Start your camera app and set the mode to front camera mode.
When the camera module is completely extended, you can remove the six Phillips screws of equal length.
The camera will automatically slide down again after some time, so you should start unscrewing the screws directly after moving the camera out.
Then use a plastic spudger to slightly lift the cover in several places and take it out.
Disconnect the battery
Battery Connector

Next, the battery contact is disconnected. This prevents any further power from circulating in the device and prevents short-circuits during the repair.
Make sure that the camera module is still extended when you disconnect the battery contact. This will keep the camera in this position for the rest of the repair.
Separate the connector with a plastic spudger. Always lever from the side where there are no small components on the board to avoid damaging anything.
Remove the speaker
7 × 3,9 mm Phillips

Connector

Loosen the seven Phillips screws of the same length that hold the speaker in place.
Then lever the slightly glued component out of the unit.
Now the connectors of the wide flex cable connecting the main board with the USB board are exposed.
Loosen the connectors with a plastic tool and take the cable out.
Remove the battery
The battery is glued very strongly into the device. To remove the battery, the adhesive must be warmed up.
Never heat the battery directly, but always from the side of the display.
You can simply flip the appliance over or you can place the heat gun on the table and hold the unit over it.
Then lever the battery out of the device gradually with a wide and stable tool such as the battery spudger.
You can also use a flat tool made of plastic to try to get under the battery bit by bit.
Here, too, it is better to heat up more often and work carefully. You should definitely avoid bending the battery or damaging its case.
Do not lever in the upper part of the battery, as the battery controller is located in this area.
Remove the USB board
1 × 2,9 mm Phillips

Antenna Connector

Fingerprint Connector

Remove the single screw that secures the USB board.
Then disconnect the connector of the fingerprint sensor.
Disconnect the connectors of the two antenna cables. Use a pair of tweezers to slide under the connector and loosen the contact with a slight turning movement.
Finally remove the SIM card holder from the device.
Now the lower circuit board can be removed from the device. Bend the cables a little bit to the side to not get stuck with the board.
Remove the fingerprint sensor

Loosen the two screws of the fingerprint sensor.
Then lever with tweezers on the left plastic guide and take the sensor out of the device.

Remove the red antenna cable on the left side and the white and blue cable on the right side from their guides in the frame.
Then disconnect the connector of the camera motor from the main board.
One of the screws that secure the mainboard in the unit is located below the camera module. Pull the component slightly upwards to loosen all five screws.
Then pull the camera module further upwards until it slides out of its lateral guides.
Take a spudger and lever the main board slightly upwards.
Now you can put the camera module together with the main board aside.
Remove the camera motor
2 × 2,9 mm Phillips

Loosen the screws of the camera motor.
The camera motor is now loose and can be taken out of the device.
Prepare the new display
Now take the new display unit and compare your spare part with the old display.
You might have to take over some small parts like the vibration motor.
Then remove the protective foils over the openings and adhesive surfaces.
We do not use a new display in this manual, as it still worked. But the assembly works the same way with a new display.

Insert the camera motor
2 × 2,9 mm Phillips

Put the camera motor back in the unit.

Screw in the plastic cover of the red antenna cable.
Insert the camera covers
2 × 2,3 mm Phillips

4 × 2,4 mm Phillips

Now insert the metal clamps on the right and left of the camera module again.
Then put the middle cover back on. Pay attention to the correct positioning. On the left metal socket a small nose protrudes, which you can use for orientation.
Then screw the covers back on. Use the black screws for the middle cover and the silver screws for the side covers.
Then put the plastic covers back in their positions. The labels "R" and "L" describe the position when viewed from the display side.
Insert the fingerprint sensor

Place the lower board back in its position in the device. Be careful not to pinch any cables underneath.
Then put the SIM card holder back in place. If it is stuck, do not push it in with force, but check if the board is already in place.
Then reconnect the connector of the fingerprint sensor.
Position the connectors of the antenna cables over their sockets and press them down with a spudger until they snap into place.
Lead the white cable into the clamp on the board.
Then fasten the single screw.
Insert the battery
Now insert the battery back into the device. If your display does not have any new adhesive surfaces, you can use thin double-sided tape to re-attach the battery.
When inserting the battery, make sure that there is enough room on all sides.
Insert the speaker

Test your Galaxy A80
Before you completely close your Samsung Galaxy A80 again and reglue the back cover, you should test if everything works.
Start the phone and open the phone app.
Enter *#0*# in the number field and the Samsung test menu will open.
Here you can test the display for touch and display errors.
You can also test all other functions, such as the speaker, vibration motor, etc.
If everything works as expected, you can close the device.
Attach the back cover
Remove all remaining adhesive from the inside of the back cover and from the frame of the device. You can scrape off the remains with a plastic tool, like a spudger. You can also use rubbing alcohol such as isopropanol and a lint-free cloth. You should remove all adhesive residue so that the device can be closed properly.
Take the new adhesive frame and check the correct alignment. You can orient yourself on different recesses and screw holes.
Pull off the first transparent protective film and place the adhesive on the frame so that it sits correctly and does not protrude anywhere.
Then remove the green protective foil. If the glue comes off the frame in some places, press it back into position with a spudger.
Then put on the back cover and press it down.
You can heat the edge of the device again with the heat gun and weigh it down with a few books to make the adhesive bond even better.
