Recently, when I turn on the camera there are numbers on the upper right corner of the screen such as 31503, in front facing mode and 7104 in rear mode.The camera has never had this problem and the pictures still turn out perfectly fine. I just don't know the numbers are there and I want to get rid of them. I'm also wondering if I wanted to reset the phone's camera would that delete my pictures? Any suggestions would appreciated!
