Proximity sensor, volume down button & reception/speaker issues
I'm new here so please be gentle...
I recently picked up a used iPh5 and it is great but has a few issues that need repair.
The proximity sensor is not working, I'm aware that this may have been a software glitch but should be resolved now that I'm on iOS 7.0.4
the volume down button doesn't work
I have experienced poor service & 'no service' in places where I previously had excellent coverage but I also suspect that the ear speaker volume could be better.
My question is this,
Could these issues be related to a damaged board or cable that serves these various components.
I'm undecided whether to open it up myself, drop it in somewhere for repair or sell it on.
I replaced the button cable and they work fine now,
I replaced the proximity sensor cable and that still doesn't work.
The issues with the reception remain.
Esta é uma boa pergunta?
