iphone 4s problem

[beehhh]

Hello to everybody, the earpiece on my iphone 4s doesnt work, event though it was changed. Does anyone know what the problem could be? Is it possible that the motherboard is the problem? Maybe because I lost the phone on the floor?

Hi



Whoever carried out the repair Ask them to check their work and the hardware they fitted.
