S6 EDGE DISPLAY PROBLEM

[junniscorpio]

Hello.
Its 2nd time that my screen display turns like this. touch works fine and after restart cell becomes normal again.
So question is. Is this any serious issue or this happens normally ?
Should I get a new one or is it normal ?

better come to samsung service center and have it checked. check also 3rd party apps that you had installed recently. it might be the cause
