I posted about the Bluetooth screeching in another area but this was incorrect.
Long story short, when using the Bluetooth option with any device, there's a terrible screeching noise after sometime. This happens with any Bluetooth device. The other thing is that if I have headphones on with the phone in one pocket, and I turn my head in the opposite direction, the phone basically freaks out and gets really distorted as if I'm losing connection. I've tried a few steps including a factory reset but the problem is crazy persistent.
