Phone "dies" when adjusting volume during call

My FP1 shuts down (not completely, but both sims lose connection, i.e. the call is lost) each time I change the volume via the buttons on the side during a call. Anyone with the same problem or an idea of how to fix it?

Some people have reported similar problems:

Is your’s related?

PS: Fairphone will release a software update in September. Some issues should not be present in the new version.

Thanks a lot, I will try to disable the mood screen and see if it helps :slight_smile:
