Iphone turns off randomly
Hello everyone,
I have an iPhone 6 16GB with iOS 8.3, I have it since Nov last year, everithing cool but since 2 weeks ago when it's in stand by, I'm not sure if is off or what, the screen don't turn on. It doesn't respont to "home button" or "unlock button" only restarting it. That happens twice a day but not always, I mean some days.
Some Ideas?
iPhone 6, iOS 8.3, 16GB
