Camera: Light Field, Manual Mode (ISO, Shutter Speed control) not working. If light field selected, after taking the picture the camera app just froze, camera says it is occupied when re open the camera app, need to restart after that. Manual control not working, only taking the "normal" auto picture whether I change the ISO or shutter speed.

Charging very very slow, take 6++ hours for fully charge the phone, even with included charger and usb cable. Battery drain issue still exist, if the battery capacity below 30%, it drops to 14% in like 2 minutes (problem since flyme 5, maybe a year ago)
