Backlight Turns On Randomly! HELP!

[midnightsrealm]

I don't think it's radio related, as it does it no matter where I am. Just sitting in my room at my desk working, my neck gets tired because I automatically look over at it when it turns on...and it turns on a lot.

Also, even when I "Lock my Device" and turn the screen off, it will light up often too...

And even when it's plugged in, it lights up often.

I do not have a magnetic case either...no case in fact.

This is just really frustrating, and not sure what to do. Sprint techs are idiots, took them 3 weeks to fix my texting issue which time stamped all incoming texts as the year 2016.
..I'm actually sick of calling them and they probably have a star (*) next to my name in their computer saying that they're sick of me calling.

Anyhow, does anyone have any idea as to what settings I could maybe fool with? It's also definitely not roaming because I tried simply turning roam off which didn't fix a thing.

Thanks you guys!
