Since latest update (ota-15) , sometimes the volla phone does not recieve calls or messages.
Need to reboot to get cals and sms working again

If I receive a first incoming call, all goes well. But on the next incoming call, the phone rings, but no sound at all. Also on outgoing call, no sound. After reboot all is ok again, but only on the first incoming call.
Happens on 20.04 stable channel and rc channel.

@duportail
setting sleep on inactivity to never seems to solve this problem
