While the screen adhesive is still warm and flexible, insert a pry tool or plastic card between the glass display and the frame of the phone.

Slowly slide another pry tool around all the edges of the phone in order to break the adhesive's bond to the display.

When using the pry tool, do not use too much force or the phone's internals could be damaged.

Do not insert your tool more than 1cm into the top edge of the phone to avoid damaging the fragile cables.
