Microphone don't work well (buzz) and it too from earphones mic
I got iphone 3gs with microphone signal problem. Microphone don't work well (buzz) and it too from headset mic and bluetooth headset mic too. I was replace microphone but nothing happened. I also reinstall ios from 4.0.1 to 4.1 and nothing too (((
Before i have 2 problems - audio jack and microphone signal, but i was repair audio jack.
So i was think that damage was in the motherboard perhaps somebody could give some working tips to solve this problem?
Thanks a lot in advance
Is this a good question?
