[AC Question]

Ok so I've had this phone a droid turbo 2 less than a month and I've been having problems with it the last couple of weeks. I can't have any apps it's seems like without the damn phone crashing so on Sunday I factory reset it by going to setting and blah blah blah and it seemed fine I only have a few apps that I downloaded on my phone and today my phone went nuts it keeps shutting off and turning on and now it only goes black start up screen and shuts off and won't stop the pattern I have no idea what to do.....please help
