Hearing volume on iPhone 6
Unable to increase volume to hear during phone calls. Ok with ear piece and loud speaker, also while listening to music or a video or playing a game, I can adjust the sound volume with the buttons on the left hand side of the phone.
Obviously, during a call I have used the volume button on the left hand side of the phone, but no change. I've checked under sound in Settings & found only one option to increase the Ringer & Alerts sound. This is not the answer to fix the problem.
Does anyone have the answer or a similar problem with their iPhone 6?
Cheers
iPhone 6, iOS 9
