My pinephone has a very limited functionality. I made updates when i booted the first time. Now i tried stable (2020-07-04), rc and dev. No cellular network (can not connect), no mobile data, no gps, no camera (should be normal). I checked the hardware buttons and turned them off and on again. The cellular network tries to connect but then is rejected. The gps does nothing. In the apps permissions i have no entries for camera, location and microphone, which is not normal. By installing unav and puremaps i was not asked to give permissions. What does the reset button on the back? Is there a way to fully reflash the phone?
