Backlight not turning on since 6.5 update

[AB_]

After the phone turns the screen off, at times it wont turn back on.

I uploaded a video of this problem on youtube, but can't post the link (as I have less than 10 posts) youtube.c om/watch?v=I4QfRyUuhkA (had to space it out in order to show you guys)


I've posted this at other boards, and even saw another person with the same issue but nobody has a solution. Appreciate any help
