Recently, I have seen several cases that their touch screen of iPhone 7 was no response/unresponsive, it is like being frozen. It makes a lot of troubles for those who have this problem. So, Vipprog wrote a wizard for this problem.
Uninstall some troublesome Apps. Some apps that use actions on your touch screen may slow down your screen's working and you may receive some lags while operating your touch screen. If this is the cause for your frozen screen, then reinstalling the appor another app replacement will probably fix all the issues with your touch screen.
Remove the case or screen protector (VC493) on your device, which might cause the screen not able to react to all of the sensitivities of the touch of a finger like it normally would.
.Try to clean the screen (VC743) with a soft, slightly damp, lint-free cloth. It is best to wipe in a circular motion.
Restart your device, which is considered to be the best and quickest method to solve the problem. If you can't restart it, you can force restart your device by pressing and holding the home button and the reset button on the top of the phone for a full 10 seconds until the phone resets and the Apple logo appears on the phone.
Resetting your phone to its original settings, you can easily do it by simply connecting your iPhone to your computer and doing its reset using iTunes. If the iPhone 7 touch screen is still not working, move to the next solution.
If none of these steps work, then the issue may be related to physical screen display defects, in such case, a broken screen repair or LCD repair could be a perfect solution.
1. Make sure to unplug your device when performing all the operations.
2. Make sure that your hands are clean and dry before starting all the operations. Any kind of moisture can affect the way the touch screen operates. Moisture sometimes slows the response time from the screen to the operating system.
