Cannot hear caller on my FP3 without reboot

Since a few weeks I got an isse that if I pick up the phone when I get called I cannot hear the caller.

Only thing fixing this is a reboot of my phone. As this happens multiple times a day, this is no longterm solution…

This seems to happen randomly, I cannot pinpoint what the source of this issue is.

Anyone else experiencing this?

What I tried to fix it, without change of the issue:

  • Check that ‘calling via wifi is disabled’
  • check in networksettings, that defaultnetwork is 2G/3G/4G auto
    -reboot of the phone
    -latest update installed
