No phone calls can be made, unless speaker is used.
Today I have replaced an display of the iphone 4S. When testing I discovered that (when placing a call) the other end can't hear me. Only weird beeping cracking sounds are heard. Putting the phone on the speaker, everything is fine. No recording can be made by the dictaphone.
I think that by assembling the phone again, the ribbon cable of the noise cancelation mic is damaged.
Which ribbon cable do I need to order, and (of course) is there a guide for this?
Appologies for my bad English.... :-)
Is this a good question?
