iPhone 6s unresponsive screen
My phone goes to the "Enter Passcode" screen, and I am stuck there as the screen is unresponsive to touch. Hit the power button and it will sleep, hit it again and it will bring up the locked screen (time, date, notifications, etc). Press home to unlock, and it's back to the passcode screen. Hold the power button to "power off" and there is not response by the slider or Cancel button. Force power off, and it reboots but the above situation does not change.
Any help greatly appreciated
