No ringtone

Hi

I have several times the problem, that I do not hear incoming calls. Some days ago my smartphone was beside me on the desk while I was working. I had an incoming call. The display turned on, but the phone did neither ring nor vibrate. I checked the soundsettings afterwards: "Mute-mode" was off and the sound was turned on. Nevertheless, the phone did not ring.

This seems to happen recently because I sometimes don't hear calls, although the smartphone is in the pocket off my trouser. I could not reproduce the error yet, it seems just to happen sometimes.

I posted the bug there: https://forum.ubuntuusers.de/topic/handy-klingelt-nicht-bei-eingehenden-anrufen/#post-8619803
Some people told me that they have the same problem, but no one had a solution, so I decided to report the bug here.

Greetings, Jojo

My system is: Ubuntu Touch, OTA 13, Aquaris E4.5
