If you notice that your iPhone screen freezes and is not responding at all, don't worry too much. This happens a lot on iOS devices. Generally, there are 3 ways to solve the screen frozen issues. I will list all of them in here.
Supported iOS Device: iPhone 7/7 Plus, iPhone 6S/6S Plus, iPhone 6/6 Plus, iPhone 5S/5/4S, iPad, iPad Mini, iPad Air, iPad Pro and iPod Touch
Supported iOS version: iOS 10.0/10.1/10.2, iOS 9.0/9.1/9.2/9.3, iOS 8.0/8.1/8.2/8.3/8.4 and iOS 7.0/7.1
A hard reset is the easiest way to fix all sorts of iPhone issues you may come across. This is just like a compute reboot. Simple and efficient. So you can use this method to unfreeze your iPhone in less than 10 seconds. Please don't let word "reset" scare you away because it doesn't erase anything from your iPhone.
Step 1: Press the Home and Power button at the same time for about 10 seconds.
Step 2: After Apple logo appears on the screen, release the buttons.
Step 3: Now, the iPhone should turn on and function like normal. If this still doesn't help, then move to Method 2.
There are a couple of cases that cause the iPhone frozen. One of the most common ones is incompatible third-party apps. If this was the case, then a factory reset or restore can solve the issue with the help of iTunes. However, the data on the iPhone would be wiped permanently. Make sure you have backed up your iPhone previously. If not, then stick to Method 3. How to restore from iTunes backup:
Step 1: Connect your iPhone to a computer and open iTunes app.
Step 2: Click iPhone icon on the upper right corner. Then move 'General' tab on the left sidebar.
Step 3: There is an option on the main windows called 'Restore iPhone'. Choose a backup and restore from it.
Step 4: After that, the iPhone should reboot as normal.
Note: If the device would not be detected by iTunes, then move to Method 3, too.
