One must / can the glass S3 while removing the old disk can not be too hot. For me, the LED has top left gotten something and green is no longer correct. You also have to make sure that you do not get too scratched the casing during peeling with a knife. Ev. the housing additionally taping the edges. Remove any old adhesive residue black adhesive foil. Remove any dirt (glass residues) and dust necessarily. Use the bottom button penetrates dust an ultimately comes into the display. Here remove the original silicone seal and carefully cut out the enclosed black adhesive stencil something and therefore good seal at the bottom of the display (not set too high, otherwise you see the glue later at the glass edge below). The small sensor film below you can stick with residues on the printed circuit board - does not have to be connected to the glass again. Necessarily look when removing the rear protective film from the replacement glass if no adhesive residue or stains are gone. Then glue the new adhesive film in the S3. After removing the upper protective film, you can use the new glass (without rear protector). Good pressing and remove the upper protective foil. Something warm and reprints the glass - ready, looks like new, and for the future but a thin silicone cover (eg mumbi X TPU) pull over it.
