My new Blu lLife One X2 keeps restarting. Any thoughts on how to stop this?

[AC Question]

I tried the factory reset from the settings menu but it didn't help.

i've been having the same problem, and it seems as if whenever it happens again its long than the previous time

A bad battery? A bad battery connection? A faulty power switch? A bad SD card?
Also, does it persist in Safe Mode?
