I have an A 21 when i turn my phone horizontal to take a pic the screen goes dark. Anyone know how to fix this?
Do you have Accidental Touch Protection on in your Settings under Display? If your finger is covering the light sensor your phone will think it's in a bag or pocket and it'll go dark while that setting is enabled. Try holding your left hand somewhere else while you take the picture and it might fix the problem too if you'd rather keep Accidental Touch Protection on!
