11 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.

Insert the battery
Now insert your new battery back into the device.
You can use the glue left in the device to reattach your new battery. Make sure that the glue does not wrinkle and remove glue from such places if necessary.
Remove all old glue from your device if your battery has new adhesive surfaces.
If there is not enough glue left in the device and your new battery does not have any adhesive surfaces, you can also use thin double-sided adhesive tape.
When inserting the battery, make sure that there is enough room on all sides.
Insert the speaker
Connector

7 × 3,9 mm Phillips

Put the wide flex cable back into the device and connect it to the main board and the USB board.
Place the speaker back in the device, press it down slightly and screw it in.
Connect the battery
Battery Connector

Now connect the battery to the mainboard.
Insert the main board cover
6 × 3,3 mm Phillips

Place the cover of the main board on the right side and then press it into position.
Make sure that the small plastic noses on both sides snaps back into place.
Then you can fasten the cover.
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.
