How to fix a new keypad:
Make sure that the PCB is clean (no remaining glue and no fingerprints on the
keypad side.
Usually the glue stays on the keypad, but if necessary clean board with Isopropanol.
Do the next steps shortly afterwards to prevent that dirt or dust gets between keypad
and board.
Peel off the protection foil of the keypad and insert it in the case shell (picture below).
Insert the board starting with the microphone area.
