Why Is My iPhone Screen Glitching?

It’s important to remember that liquid damage or a cracked screen aren’t the only possible causes of a glitchy iPhone screen. There are a number of reasons why an otherwise flawless iPhone’s touch screen could not work. The following are some of the proposed reasons for this issue:

Auto-Brightness Settings

As you walk about, the quick change in light intensity might cause your iPhone’s screen to flicker if your auto-brightness option is set up to adapt your phone’s brightness based on the amount of available light.

Bugs in iOS

Bugs in Apple’s mobile operating system (iOS) may be to blame for the erratic behaviour of your iPhone screen since they lead you to change the settings of your screen’s display. Surprisingly, the newest version of iOS 15, has security bugs.

Corrupted software

That might potentially be the cause of the glitching on your iPhone’s display. It is the job of the GPU, or graphics processing unit, to create the visuals that you see on your screen. The GPU and the software of an iPhone are prone to causing graphic issues.

Hardware problems

Your iPhone’s screen glitching might be due to issues with the internal parts that provide the screen’s display. A spill or drop may cause serious damage to hardware.

How to Solve iPhone Screen Glitching?

Since we know what’s causing the iPhone’s display to flicker or glitch, we can move on to the solution. In this part, you’ll find answers that are likely to fix the iPhone bug you’ve been experiencing.

1: Force Restart

A hard restart of your phone may help cure a variety of technical difficulties that you may be experiencing with it, including an issue with the display on your iPhone. If you’re experiencing this problem after installing iOS 15, this solution will help.

If you have an iPhone 8 or later, you can perform a force restart by pressing and quickly releasing the volume down and up buttons, and then pressing and holding the “Side” button until you see the “Apple” logo.

2: Turn Off Auto-Brightness

Check the Display Accommodations section of Settings to see whether Auto-Brightness has been disabled. If the toggle is active, you should deactivate it by touching it, after which you may leave the settings menu.

Turning this off will help keep your screen’s brightness where it should be and lessen the likelihood of any instances of flickering or glitching.

3: Force Quit a Particular App

If your iPhone’s display glitches whenever you attempt to launch a certain app, you may forcibly quit that application by double-clicking the Home button or swiping up from the iPhone’s home screen. Selecting this option will display all the apps currently running in the background, allowing you to pinpoint the problematic application.

Then, to close an application, just slide it up and off the screen with your finger. Apps that are known to cause flickering or glitching on the iPhone screen may be quickly stopped using this method.

4: Update Software

The usage of outdated software is a frequent contributor to display issues. Your iPhone, like any other computer, is useless without the right software.

Newer versions of this software are always being published to address user feedback and improve the software’s overall quality and efficiency. Your iPhone’s display might well be acting up because an update is available.

5: Restore iPhone in DFU Mode

If your iPhone’s display is flickering or lagging, you may get it back to normal by doing a DFU restore using iTunes or Finder.

Restoring your device to its original condition requires a sophisticated procedure known as a DFU or Device Firmware Update.

Important Note: Restoring your iPhone while in DFU Mode will roll back your iOS version and delete all of your data.

6: Reset Your iPhone

If you’ve already attempted the aforementioned steps and your iPhone’s display is still malfunctioning, a factory reset may be the ultimate solution. This will permanently delete all of your information, including your phone book, images, and text messages. Back up your files first to avoid losing anything before proceeding.

  • Go to Settings
  • Tap on General
  • Now Choose “Reset”
  • Tap on “Erase All Content and Settings” and Confirm it

After that, an option to factory reset your iPhone will be given to you. You should only use this as a very last resort after you’ve tried everything else.


If your iPhone’s display remains unresponsive after doing the aforementioned troubleshooting steps, you may want to contact an expert. The good news is that your iPhone can probably be fixed by one of the several trained professionals available.

Usually, they won’t have to delete any of your information to achieve this. Finding a competent local technician may be difficult, but you can always do some research online. In today’s digital era, it’s easier than ever to search for and connect with a local expert in any field.

You should do everything you can to extend the life of your iPhone’s functional condition. If you adhere to the aforementioned solution, you should be able to prevent a lot of the most typical issues with displays.
