iPhone 5 No sound/mic during calls – iphone mobile hardware strange problem
I have an iPhone 5 64GB that I am trying to fix, the issue is that during calls I cannot hear anything and also the caller at the end cannot hear anything either. I have tested the MIC and Speaker via the voice memo and via the video recording and they all work fine. I have even tried replacing the noise cancelling mic, the charging dock (mic) and the speakers. I have restored the phone multiple times but Along with no luck.
I am wondering where I should start Along with a board level repair, what should I try and reflow/replace first? I have all the equipment to do so at my work.
Thanks in advance for any to be helped you can give me.
