Clean iPhone’s Screen
If you get water droplets or any other particles, such as sand, dust, or dirt, on your iPhone’s surface, it can interfere with the touch sensitivity of our phones. Therefore, clean your iPhone’s screen regularly.
Before you begin, unplug any cables from your iPhone. Now, place your device properly on a stable surface.
After this, you can use a 70% isopropyl alcohol wipe, 75% ethyl alcohol wipe, or Clorox Disinfecting Wipes to clean your iPhone’s touchscreen.
There have been reported issues with screen flickering after users updated their iOS software. This could be due to a software bug.
Since Apple launches such bug fixes on their next software update, you must keep a check for the newer version of iOS and update your device.
If your iPhone’s touchscreen has minor hiccups, you can go to Settings>General and tap Software Update. If you see multiple software update options, pick the one you want to install and Tap on Install Now.
For situations where your touchscreen is not responding, use a computer to update the iOS. If you’re using Mac or Windows, Download and Open iTunes. And then continue with the following steps:
Connect your iPhone to your Mac/PC.
Locate the iPhone option and click the device button in the iTunes toolbar.
Click Check for Updates from the summary tab.
Now, click Download and then Update.
If the abovementioned methods do not work, you can consider doing a factory reset. This can help to resolve software issues in your iPhone or if any third-party app has caused some malfunction to your device.
You can quickly factory reset either via the Settings option or iTunes. But remember that this action will wipe out all your personal data from your iPhone.
To factory reset, go to Settings, then General, and tap on Transfer or Reset. Tap on Erase All Content and Settings. Then tap on Continue, followed by Erase iPhone.
For those whose iPhone’s screen is stuck and they are unable to go to the Settings option, the best alternative is to connect your iPhone to a Mac or Windows PC and perform the factory reset.
Download and open iTunes on your Mac/PC.
Switch off your iPhone.
Plug your iPhone into the Mac/PC. Then, press these buttons:
iPhone 8, iPhone 8 Plus, iPhone X, and later, including iPhone SE (2nd and 3rd generation): Hold the side button of your phone
iPhone 7 and iPhone 7 Plus: Keep pressing the volume down button

Release the button once you see the recovery mode screen on your iPhone.
On your Mac/PC, click Restore, then again Restore.
