So if I relock my boot loader with stock ROM the warranty will still be void?
2 microphones? As in one for calls and one for the camera? The camera mic works just fine but the one for calls seems to be completely broken no matter how I hold my phone. I just had a phone call and when I answered, the person on the other end could not hear me at all. I had to switch to speaker phones so it could use the camera mic instead.
EDIT: Okay, so I just tried to set my own voice mail in order to playback my calling voice. I'm not joking, I sound just like Stephen Hawking except that you can barely hear what I'm saying. It is very robot like and distorted. Also, it seems like there is a voice recognition thing on, which means whenever I stop speak, the mic will turn off to reduce ambient noise. However, this also removes the first word I say when it activates the mic again upon voice recognition. I turned the noise cancelation setting off but no major difference.
And btw, the problem only seems to exist when I'm in a call, not when recording my voice with an app like WhatsApp or any sound recorder from Google Play. Even the built-in voice recorder works fine. Does this have something to do with my carrier?
