I have an HTC One (M7) and I am having a problem with the in-call volume being too loud. Even when turned to the lowest setting, I can hold the phone 18 inches from my face and hear the conversation perfectly. I work in an office and my cube-mate can hear my calls.
I have tried turning the call volume all the way up and then all the way done - No joy.
I have done a factory refresh and re-installed my apps - No joy.
I have confirmed the setting relating to hearing aids is off. - No joy.
I have Tried it with Batas Audio on/off - No joy.
Any other ideas. I am extremely frustrated with all of the Google searching that I have done to address this. Has anyone else seen this and solved it?
