Hi,

I am getting black and white diagonal lines on my Samsung Phone screen when watching the camera view when flying but on playback they are not there. Obviously this obstructs my view when flying which is very annoying.

Anyone know why this is happening?

Hi babis, have you checked your camera settings? please try to turn off "over exposure warning" on the APP or reset camera settings.
If still same case, please provide a screenshot here, thanks.

Have you read the manual babis?

It's spelled out quite clearly - over exposure warning.
