Iphone 7 Fix Touch not working after Restoring back up

One of my client's iphone 7 after restoring back his previous backup of his former iPhone 5 to the new iPhone 7 the touch stopped functioning, its kinda weird because he has never experienced something like that before.

but in my experience Apple tend to conflict ios versions so i figured out that could be the reason. unlike cases where if a backup has been made lets take for instance from ios version 11.4.1 and you tried restoring to another iPhone with a lesser version lets say 11.1. apple will require you to update the iphone to the earlier version the back up was made from which is 11.4.1 or later version.

i think it has something to do with security. but which ever the case may be here was a quick step i took to get back my clients iPhone 7 working again.
