I've recently experienced the microphone issues a lot of you have been experiencing, but also speaker issues. I thought it was best downgrading from .569 to 18.104.22.1683 (AT&T official) and taking my device to an AT&T store if the problem persisted.
Well, I noticed that my microphone problem was resolved, but I still had problems with my speaker.
My speakers work pefectly when using speakerphone, listening to music, or using any other media. But I cannot use the handset for phone calls. I've tried reinstalling the OS and numerous battery pulls. The problems started rather randomly. My phone never touched any moisture or anything else that I know of that could have caused these problems.
I spoke to an AT&T rep and he told me to claim warranty. He was quite confused himself!
Has anyone else experienced these problems? Is this hardware-related or is it software? Any fixes?
