I have a new 6s Plus. I keep having random issues with the phone: -Sometimes the display becomes unresponsive and freezes. -The touchID fails until I unlock the phone and relock to try again. -When I start a phone call from my contacts list, there is no sound on my end. -The phone has randomly turned off and the home button gets really hot. (known issue, I know) Anyone else having these types of issues? Should I wait it out or make an appointment with Apple?
