In call volume low in iPhone 12
Everything was fine, but today my phone incall volume is really low to the point I can't hear anyone on the phone. I put people on speaker and that function works like normal.
I have followed different steps to try and rectify the issue with no luck. I did notice when change the Audio balance control in the settings to the right it was very low and could hear much.
trying to work out what is wrong and how to fix it?
