Nexus 4 Suddenly Cannot Hear Anything During Phone Calls

[m.mistroni]

Hi all
since this morning i cannot hear anything when doing phone calls on my Nexus4
I havent installed any new application since about a month.
This morning i tried to call mobiles or landlines but coulld not hear anything at all

I have rebooted in safe mode, no improvements
Theni restored factory settings, no improvements

The installed android version is 5.1.1 and the kernel version is 3.4.0-perf-gdffc258 and right now i cannot use my phone at all... could anyone help at all?

kind regards
marco

If you've tried safe-mode, and tried a factory reset - that pretty much eliminates a software issue. It's quite possible you have a hardware failure (hope not!).
