My 4S needed a power button cable. When I removed the earpiece speaker it was almost impossible not to tear the foam seal that attached the speaker to the ribbon cable. It was stuck on the ribbon and the seal tore easily. After I reassembled the phone the earpiece speaker is very faint. I believe that the ribbon acts as a sound board for the speaker so if the foam seal is damaged, as mine is, it will significantly reduce the speaker volume. I ordered a new speaker, I will post my results.
