How do i unfreeze my iPhone 7 when it is stuck on the lock screen? What do I do? My iPhone screen is completely frozen. I've pressed the power button by itself to turn my phone off but when it cut back on it was still frozen, so I have no way into my phone.
According to this site, you press and hold the Power Button. While holding the Power button down, press and hold the volume down button. Continue holding these buttons until you see the Apple Logo after the power comes back on.  See image below.
