Introdução

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.

Chris Fer - Responder

il me semble que le backcover du a50 est en plastique, le chauffer trop fort risque de le deformer

Getha Cruz - Responder

Effectivement une température de 65°C environ pendant 5 minutes suffira pour ramollir le sticker située sous la plaque arrière.
