Hey guys,[br]
I’ve came across many iPhones with this issue:[br]
While calling, people cannot hear me (bottom mic), or very quietly. [br]
Using the speaker function (front mic) the problem is not always fixed. [br]
I’ve tried a software reset, replaced the dock connector with bottom mic and front flex cable. I even replaced the receiver / speaker / display (all original Apple parts).
Seen 100+ iPhones with this issue and cant seem to find the solution.
