hi all, my cell started showing some strange kind of screen flickering, its not the whole screen but some portions at a time, I made a video to make things fully clear, here it is.

Can you please tell me whats happening, I havent gone to any repair guys yet, i wanted to show it on this forum and get some feedback first.

ps: can a youtube video be posted such that it plays inline here at tmo instead of clicking and opening a new tab to play YT vids?
