The constant glitching of your iPhone can be very annoying and completely ruin the smartphone’s great features and functionalities. This goes to show why this is one of the highly debated issues among tech enthusiasts. If you’re experiencing a similar issue, you should find out what’s causing it in the first place and consequently know how you can resolve this issue. 

Quick Answer

The flickering issue of your iPhone can be caused by a couple of reasons, including bugs in your iPhone’s operating system, auto-brightness settings, corrupted iOS software, or hardware issues.

This guide will take you through a more in-depth look at the reasons behind the flickering of your iPhone screen. You’ll also learn how to resolve this iPhone glitching issue and have a better time using your iPhone. Let’s get started. 

Bugs in the Operating System

The glitching of your iPhone is sometimes caused by bugs in the iOS that corrupt its overall functionality. This issue is nowadays common in the recently released iOS 15. The presence of bugs in your iPhone eventually causes the flickering of the screen, making it hard to do anything. 

You can resolve this issue by hard resetting your iPhone, which effectively removes all the things that affect its smooth functioning. But before you do a hard reset, back up important data such as music, contacts, and photos; otherwise, you’ll lose it for good. Here are the steps to follow when doing a hard reset of your iPhone.

  1. Go to the Settings app
  2. Tap on “General”
  3. Go to the bottom section and click on the option “Transfer or Reset iPhone”
  4. Tap on “Reset” and select the “Reset All Settings” option. 
  5. Click on the option “Done” after entering the passcode. 

Once you’re done, your iPhone will start to reset itself by restarting, and this should take a couple of minutes. After your iPhone restarts, the screen will no longer be flickering because all the bugs will have been removed. 

Auto-Brightness Settings

Another reason your iPhone is constantly flickering is incorrect settings in the brightness sensor. This usually happens when your iPhone’s brightness settings are configured with a light sensor to change the screen’s brightness. As a result, a quick change in light intensity when moving your iPhone might cause it to start flickering. 

This issue of incorrect setting in the brightness sensor is also a common reason behind the glitching in Android smartphones. This issue is easily resolved by disabling your iPhone’s adaptive or auto brightness that keeps changing screen illumination. You can do this by following the steps below.

  1. Go to the Settings app
  2. Click on “Accessibility”.
  3. Tap on “Display & Brightness”
  4. Switch off the “Auto-Brightness” button.  

After making this adjustment to your iPhone’s settings, the issue with glitching will stop altogether. 

Hardware Issues

If your iPhone has hardware issues, such as damage to an essential component, such as the display circuit board, it might start to flicker. Such an issue may arise if your iPhone accidentally gets dropped into the water and gets damaged as a result. However, this won’t happen immediately after your iPhone gets submerged in the water but at a future date. 

Besides falling into the water, hardware problems may also arise due to a fall. You can only repair hardware issues by taking your iPhone to the Apple Genius Bar or a professional accredited by Apple to try and resolve the issue. 

Problematic Apps 

Problematic apps can also cause the flickering of your iPhone, and this happens because these apps are outdated. Because of this, closing or forcing a restart of these apps doesn’t work quite well at resolving your iPhone’s constant flickering. 

If you suspect the problematic app is causing your iPhone’s glitching issue, the best thing to do is to update it. Doing this is rather simple, and here are the steps you need to follow.

  1. Go to the Home screen of your iPhone. 
  2. Launch the iOS App Store
  3. Go to the top right-hand corner of your screen and click on the Account icon. 
  4. Scroll to the bottom section and click on the “Updates” option. If there’s an update available for the problematic app, click on “Update”. You can also click on “Update All” to download updates for all the apps simultaneously. 

If updating the problematic app doesn’t seem to work, the other thing you can do is delete and reinstall it once again on your iPhone. You can do this by following these simple steps.

  1. Press and hold on to the app you wish to delete. 
  2. Click on the “Remove App” option. 
  3. Tap on “Delete App”
  4. Press “Delete”

After uninstalling this app, proceed to the Apple App Store and download and reinstall this app. Once the download is complete, the app will be installed on your smartphone. 

Corrupted Software 

The iPhone glitching can also be due to corrupted software. This happens when the GPU tasked with producing images that appear on your iPhone’s screen is incompatible or in conflict with the installed software. As a result, this is what causes your iPhone screen to start glitching. 

You can restore your iPhone to normal settings by formatting your iPhone to restore it to its original state.

  1. Click on Settings
  2. Go down and tap on “General”
  3. Scroll down and click “Reset”
  4. Click “Erase All Content and Settings”
  5. Enter your iPhone’s passcode if requested. 
  6. Click on “Erase” to proceed even after getting the notification to delete all the media, including music, pictures, and other data. 

Give it a few minutes, and your iPhone will be reset as if it’s new and the corrupted software is done away with for good. 


After using your hard-earned money to buy an iPhone, which doesn’t come cheap, the last thing is to no longer enjoy using it due to constant glitching. When this happens, your iPhone becomes unresponsive. As a result, this makes the overall usability of your iPhone a lot harder and more frustrating, which is the last thing anyone wants with their smartphone. 

But after reading this guide, you’re now aware of why your iPhone is continuously glitching. With the insights discussed above, you now have an idea why your iPhone’s screen keeps flickering, making it hard for you to access your smartphone. You have also learned how to resolve the issue and enjoy using your iPhone better.
