Introduzione
If your touch screen is broken, cracked or defective, use this guide to replace a broken screen on your Samsung Galaxy A50 (SM-A505F).
For your information, the screen product codes of a Samsung Galaxy A50 are: GH82-19204A or GH82-19713A.
'Before disassembling your phone, it is advisable to discharge the battery of the Samsung Galaxy A50 below 25%.' Otherwise, if you accidentally puncture or damage the battery during repair, the battery may catch fire or explode. These risks are lessened if the battery is mostly discharged.
Note: Replacing the screen includes removing the back of the phone, which means you will need a new piece of back adhesive.
If you damage the frame, you will need to replace it, as a damaged frame could result in uneven pressure on the screen, permanently damaging or destroying it.

il me semble que le backcover du a50 est en plastique, le chauffer trop fort risque de le deformer
Done, finger print sensor won’t work any more, everything else is.
