Hello. A few hours ago my phone (samsung s7) started to display some green dots on black background (only on black, no other colors) and green lines in gallery and camera (on black spots). It might be a bug or something...the phone was kept on my desk, near me, no damages, those green things just random popped up and i do not know what to do...the screen is not damaged and the phone is just 2-3 months old.
Also those green lines are appearing only on the half left side of the phone and also those now appear on facebook, when watching photos there are some black edges above and below the photos, and the green vertical lines appear on them.
Large number of green dots appear in camera too.
Some help? What might be the problem? Sorry for bad english, im not a native.
