I have got some problems with my 5Z.
1st: If bluetooth is on or was on and I get a call, on the screen it is not green button to pick up the call. I can only pick up the call with a bluetooth accessories. I have to restart my handy (after restarting it operates well until the first using of bluetooth). If I start a call from telephonebook, I haven't got sccreen with green buttons. I can't see when the call will be answered.
2nd: If I use the information button (see the red marker on the first pic) on telephone menü, the call history of the partner is missing (it is empty - see the green marker on the secobd pic).
Are these due to a botched update? (I'm NOT using a rooted phone, so it only updates from Google Play)
3rd: why can not I update my handy from January in 2021? Neither android nor security updates are coming (Android 10 remains).
