After using headphones with my HTC ONE (M8) yesterday, the phone now randomly thinks there is a headset plugged into it. Thankfully, I have not yet had calls affected by this, but with the phone thinking that there is a headset with microphone attached, if I do get a call and it switches into "headset mode", I'm assuming that the caller would not be able to hear me, because the phone would be looking for a microphone that isn't there! The phone is just over 30 days old, please help!
