Hey Guys, So earlier today my iPhone 6 froze out of nowhere then it went black and now the screen won't turn on. If i toggle the mute switch on the side it still vibrates. When I plug it into my car, music from my phone still starts playing. But still no screen. Is there a way to force restart the phone by holding a combination of buttons? This is really weird.. Should I wait for the battery to die, or try to walk it into an Apple Store?
