Solution 2: Hard Reset Your iPhone (Erase All Data and Settings)

If there is a change in your iPhone settings that is causing its screen to flicker or glitch, then you can hard reset your device. Ideally, it will erase all the saved data or configured settings on your iPhone and would restore its default values.

Therefore, if your iPhone’s screen is glitching due to changed settings, then this would do the trick. To fix your iPhone, just unlock it, go to its Settings > General > Reset, and tap on the “Erase All Content and Settings” option.

Now, you just need to enter the passcode of your iPhone to confirm your choice and wait as your device would be restarted with factory settings.

Solution 3: Reinstall Specific Malfunctioning Apps

A lot of users have encountered that the iPhone 11/12 screen glitching issue happens for specific apps. For instance, if you play a specific game that is not supported by your iOS device, then you can encounter a screen glitch like this. To fix the iPhone screen flashing green issue due to a corrupt or outdated app, you can consider reinstalling it.

At first, launch the app and check whether the iPhone X screen flickering issue is persistent or specific to the app.
If the problem is with the app, then consider uninstalling it. Just go to the home screen of your iPhone and long-tap any app’s icon.
As the apps would start to jiggle, tap on the cross button above the icon and choose to uninstall the app.

Alternatively, you can also go to your iPhone’s Settings > Apps, select the malfunctioning apps, and choose to delete it from here.

Once the malfunctioning app is deleted, you can restart your device, and again go to the App Store to manually install it.

Solution 4: Check the Memory Status of your iPhone (and Make Free Space)

Needless to say, if there is not enough space on your iOS device, then it can cause unwanted issues in it (like the iPhone screen flickering to green). That’s why it is always recommended to keep at least 20% space on your iPhone free for its processing or any other activity.

To check the available space on your iPhone, just unlock it, and go to its Settings > General > iPhone Storage. From here, you can see the available space on your iPhone and even check how its storage has been consumed by different data types.

Subsequently, if you want, you can directly offload any app from here to make more free space. You can also get rid of your photos, videos, music, documents, browser data, and follow other tips to free up iPhone storage.

Solution 5: Disable the Auto-Brightness Feature on iPhone

Just like other smart devices, iPhone also offers an Auto-Brightness feature that can automatically adjust the brightness of the screen. Though, it has been observed that the specific setting can cause unwanted issues like iPhone XS/X/XR screen flickering.

To fix this problem, you can just disable the Auto-Brightness feature by visiting your iPhone’s Settings. Unlock the device, go to its Settings > General > Accessibility > Auto-Brightness, and manually toggle it off.

Solution 6: Enable the Reduce Transparency Feature

Apart from the Auto-Brightness option, the transparency setting on your phone can also cause the iPhone screen glitching problem. For instance, iOS devices have an inbuilt “Reduce Transparency” feature that would improve the contrast and overall accessibility of the device.

Some users were able to fix the iPhone screen flashing issue by simply enabling the option. You can also do it by visiting its Settings > General > Accessibility > Reduce Transparency and turning it on.

Solution 7: Restore your iPhone by Booting it in the DFU Mode

Lastly, if nothing else seems to fix the iPhone screen flickering issue, then you boot your device in the DFU (Device Firmware Update) mode. By taking the assistance of iTunes, it will let you restore your iPhone to its factory settings. Though, you should note that the process would erase all the saved data on your iPhone and will reset the device.

Therefore, if you are ready to take that risk, then you can fix the iPhone screen shaking or flickering issue in the following way.

Step 1: Connect your iPhone to iTunes

At first, just launch an updated version of iTunes on your computer and connect your iPhone to it via a lightning cable. You can just turn off your iPhone now and wait for a black screen to appear.

Step 2: Boot your iPhone in the DFU mode via correct key combinations

Once your iPhone turns off, just wait for a while, and apply the following key combinations to boot it in the DFU mode.

For iPhone 8 and newer models

Press and hold the Volume Down and the Side keys at the same time on your iPhone for at least 10 seconds. Afterward, only release the Side key and keep pressing the Volume Down key for another 5 seconds.

For iPhone 7 and 7 Plus

Just hold the Power and the Volume Down keys at the same time for at least 10 seconds. Afterward, only let go of the Power key, but keep holding the Volume Down key for 5 seconds.

For iPhone 6 and older models

Hold the Home and the Power keys on your iPhone for the same time. Keep pressing both the keys for 10 seconds and only release the Power key. Make sure that you press the Home key for another 5 seconds and let go once your device enters the DFU mode.

Step 3: Restore the connected iPhone

Please note that the screen of your iPhone should remain black (and you must not restart your iPhone). Once iTunes will detect that your device has entered the DFU mode, it will display the following prompt, letting you reset your iPhone.

Pro Tip: Check if there is a Hardware Issue with your iPhone

I have only included different ways to fix the iPhone screen blinking issue caused by software-related issues. Chances are that any hardware or water-damaged LCD or connecting wires can also cause this problem. In this case, you can visit a nearby Apple Service Center to get your device fixed.

If you want, you can also disassemble your iPhone and manually change its LCD unit. You can buy a compatible hardware unit online and can attach it with the relevant port while assembling your iPhone. Though, if you don’t want to take any risk, then consulting a trusted representative would be an ideal choice.
