I have tried just about everything and cannot find a solution to this. I have searched and searched and cannot find an answer to my problem so I'm hoping SOMEBODY can help me out. I have an AT&T HTC One, s-off, running the latest Cyanogenmod 11. Ever since I flashed my custom rom, calling will not work correctly. When I'm on speakerphone people tell me that I'm ridiculously loud almost like I'm screaming and when I'm not on speakerphone they say I'm extremely quiet like I'm far away from the phone and my voice cuts in and out.
Now I have no idea what could be causing this. I've tried about 15 different radios and they're all giving me the same result. Also, when data is enabled, I watch my icon continously cycle through H+, H, and 3G the entire time data is enabled and I cannot figure out what is causing that either.
Any help or insight on this would be greatly appreciated as I've been rather irritated with my phone as of late.
