phone magically turns on when powered off

[Deviyl]

Just like the title says.. I hold down the power button, it asks if I'm sure, I say yes, it powers down. It'll stay off for ~15 seconds then it just magically turns back on.

I've hard reset already with no luck. I'm about to flash stock to see what happens. If that doesn't fix it, I guess I'll see what Sprint says.

This is a new phone, by the way.. replacement from insurance claim. Maybe they just sent me a bad one..?


Edit:
Stock ROM now. Still doing it.. =\
