How To Fix The Samsung Galaxy A33 5G Screen Flickering Issue

In this article, we will walk you through in troubleshooting your Samsung Galaxy A33 5G that has a screen flickering issue. There are a number of reasons to consider that Samsung Galaxy A33 5G screen is flickering. It could be due to a minor firmware issue or your device has a hardware problem. 

But since we are not sure what really causes this issue to occur, all we need to do is to rule out each and every possibility until we can determine the issue and fix it.

First solution: Force restart your Galaxy A33 5G

Screen flickering issues are sometimes caused by a minor firmware issue, and it can be fixed by a simple restart. Performing a force restart will refresh the memory of your phone and close all apps and services running in the background. So, if this is just a minor firmware issue, then this procedure will surely fix it.

Here’s how:

1. Press and hold the Volume Down button and don’t release it yet. 
2. While holding down the volume button, press and hold the Power key as well. 
3. Keep both keys held down together for 15 seconds or until the Galaxy A50 logo shows on the screen.

After the reset, use your phone and see if the screen is still flickering. If so, proceed to the next method.

Second solution: Boot your phone in Safe mode

Performing this method on your phone will eliminate the suspicion that one of your third-party apps is causing the issue. Booting your device in this mode will disable all third-party apps and only the pre-installed apps will run in the system. So, if the screen of your device is not flickering while in this mode, then obviously one of the third-party apps you installed is causing the issue, and you need to uninstall it to resolve the problem.

This is how you do it:

1. Press and hold the Power key until options show. 
2. Tap and hold the Power off option until it changes into Safe Mode. 
3. Tap the Safe mode icon to restart your device.
4. Once the reboot is successful, you should see ‘Safe mode’ at the lower-left corner of the screen. 

However, while in safe mode and the issue continues, then proceed to the next method.

Third solution: Reset all settings

Sometimes, due to misconfiguration you’ve done on your phone, other features are affected and causing different issues on your device and one of them is screen flickering problem. So, to eliminate this suspicion, we suggest that you should do a settings reset. Meaning, you have to bring your device settings back to its factory default.

2. Tap the Settings icon on the upper-right corner. 
3. Scroll to and tap General management. 
4. Touch Reset. 
5. Tap Reset all settings. 
6. Tap the Reset settings button.

8. Finally, tap Reset.

Fourth solution: Wipe the cache partition

Performance issues in Galaxy A33 often occur if the files and data of your phone are corrupted. If this is the case, then wiping the cache partition is recommended so that those corrupted files and data saved in the system will be deleted and replaced by newer ones. Don’t you worry, this method won’t delete your saved files on your phone.

1. Turn off the device.
2. Press and hold the Volume Up and Power keys.

After wiping the cache partition, use your phone again and see if the screen still flickers. If so, move to the next method.
