Chosen Solution

Hurt my fingers pressing the buttons. Can I just take it apart and try to clean them? It’s my old phone but don’t want to throw it.

Last time i had that happen, i disassembled the phones and cleaned the connections real good with some 70% alcohol. But it only fixed the problem for a few months. The problem is mostly the rubbery stuff they used to make the contacts starts to harden, and become trash.
