Hi, I'm experiencing an issue with my screen unlocking during Bluetooth calls. I keep my HTC One in my pocket and when a Bluetooth call is initiated from my Bluetooth kit in my car, the screen unlocks and stays on. When the call is finished the screen stays on and I'm having an issue with "buttons" being pressed and starting texts, dialing people, etc. I've also found that if I lock the phone after the call is initiated, the phone is again unlocked when the call is ended. I'm using one of the built-in lockscreens without a passcode. Is this how the phone is supposed to function? If so, any workarounds or apps to resolve this? Thanks!
