I too am having an occasional problem with the camera. For some odd reason my camera GPS tag function will automatically be turned off. Moreover, photos taken without GPS tag will cause edit photos from not arrange properly in the library.
Was taking some selfie pictures with my mate 20 pro and found some weird lines on the pictures. AI HDR was off and I am wondering if this is a hardware or software problem. After restarting the phone, the problem seems to be gone but I suspect it might come back!
If this is a software issue...
