So I've had my X for a couple days now, (Previously owned by my dad for a month or two) and the bottom of the screen was getting blurred and messed up, only about a centimeter high, and across the width of the screen. It was like this for about an hour or two and now its fixed. Will this spread? or will this just disappear? debating about taking it in. I can see the screen bug out every once and awhile in the same spot, but hasn't quite gone back to how it was before.
