During office hour, normally i minimized the volume till zero amd when ppl call... they cant hear me but i can.. so during call i max the volume... i can hear them quite loud but they cant hear me.
After work hour i turn up the volume... normal call they can hear mine...
I don't not use the silence mode
Why?? Is mic volume controlled by the same??
Damn laaaa last time mo such issue now recently got
Soft reset your phone bro, if you have not tried it. Data will not be erased. Press home button and power button together and hold, until the phone blanks and then the apple logo reappear, only let go of the button. The phone will restart. Key in your passcode and then the passcode to unlock carrier. See whether this resolve your issues.
AFAIK, we can't adjust how loud the listener can hear. But we can mute the call so that other side cant hear you but you can hear them.
Hope the reset can resolve your issue.
