Lock screen, backlight flashing on and off!

My boss mans 8330 with sprint, when you lock the phone, every 3-5 seconds the backlight when come on, then 3-5 seconds later it goes off again! This continues as long as its locked. He hasn't downloaded anything new, his been running the same 4.5 for about 5 months! Any ideas? Thanks guys?

Hate to bring up the old tired answer but have you tried a battery pull on it? Might not be a bad first effort to eliminate the easy stuff.

Thanks for the suggestion! I'm the king of BP's lol. We tried that and the issue is still occuring. Idk what's going on with it!

I was experiencing the same exact problem. I did a soft reset of the phone.

Alt + right shift + delete, and now - no flashing.

Try that!
