Iphone X touchscreen unresponsive
I was wondering if anyone could help me with this situation. It happened suddenly and I do not think I did anything to make it occur such as drop it or damage it in any way. The screen is unresponsive to any touch but the side buttons all work. I cannot even open my phone or unlock it because of this. I have tried to hard restart it and it still is unresponsive. I have tried to plug my phone into my macbook to reset it or check for an update and it says that I have to unlock my phone first before I can use the usb accessories but I cannot unlock it. Please let me know what I should do.
iPhone X, iOS 12.1
