hello everybody , i am using the jolla c2 for a while and sometimes it happen to me then i call somebody that the for example -finish the call - the button etc . is pop up 1-2 second and then the screen getting black , my solution is for now just restart my phone after this . somebody else with this issue .
This is a behaviour i have too with a Xperia 10 II and always had. Sometimes call screen will get black. Its probably a bug, but it was never resolved somehow…
