garbled voice with 4.4 ROMs on T-mobile
I have the same issue on T-mobile. Using any 4.4 ROM results in my voice fading in and out during the call. ROMS based on stock work fine.
I have tried the kitkat in-call audio fix, and it does not help.
I think the problem is due to the noise cancelling microphone on top of the phone. If I cover up the small hole at the top with my finger during a call, the voice quality gets a little better, but still very faint.
Anyone know how to disable the top microphone?
