calling

[Husnain1996]

I have an Xperia Z, and whenever I ring someone, I cannot hear them nor can they hear me, but all my speakers and microphones are 100% working

Check for microphone noise suppression or slow talk,disable them.

Try to call someone in safe mode:

It was probably a simple glitch,hope it won't come back again.
