yesterday went to senQ and found there was a display unit for oppo find x9 , like the internet say , oppo seen like having focusing problem , like if i open camera and just do a quick snap , it like focusing other object rather than the front object , not sure why , so to overcome this problem , u need to tap the screen object to focus before want to snap  , which i found quite annoying , not sure they do any fix in the latest OS? Because i assume that display unit should be already on latest update OS but yet stil appear this problem

good to heard that , it shame that if the display unit doesnt using the latest firmware , definitely will make customer first impression bad due to the miss focusing problem
