Hi. Can anyone help me out? My asus zenfone 6 suddenly started flickering vertical lines every 2-3seconds. It has never been dropped or wet. It continues to flicker everytime the screen is on. Really bad flicker half bottom of the screen. But all other functions are ok just this annoying flicker. I tried booting & factory rest, disable hw overlay but still flickering. This is a exampe video link of the problems i'm having with my zenfone. http://youtu.be/gphJq1SuQDM Does anyone else having this problem? Does anyone know how to fix this? Is it covered in the warranty? Thank u.
