Troubleshooting Galaxy A50 with screen flickering issue

One way to know if the screen flickering issue with your A50 is due to a hardware issue or damage is to check the device or some signs of physical or liquid damage. If the phone was dropped on a hard surface and then this problem started, the drop should have left some scratches and dents. If you use your phone underwater or if it got splashed with water and then the screen flickering started, then it’s a liquid damage. But assuming that your phone doesn’t have any signs of physical or liquid damage, then here’s what you should do: 

First solution: Force Restart your phone

When troubleshooting a smartphone, you must start with the forced restart especially if there’s a chance that it’s just an issue with the firmware. The forced restart is actually a simulated battery removal that will refresh your phone’s memory and reload all its services. If the flickering screen is just a result of a minor glitch or firmware issue, then this procedure will fix it. Here’s how you do it: 

  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 reboot, try to see if the screen flickering issue continues. If it does, then move on to the next procedure.

Second solution: Run your phone in safe mode

Running your phone in safe mode will temporarily disable all third-party applications. It is possible that one of the apps you installed is causing the screen to flicker and that’s the purpose of this procedure. Follow these steps to run your phone in safe mode: 

  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. 

While your phone is in this mode, try to see if the screen flickering issue is fixed. If the problem doesn’t occur, then it means there’s an app that’s causing the issue. Do the following to determine the app that triggers and flickering and fix the problem: 

  1. Restart your phone normal to boot into standard mode. 
  2. Remember the apps you installed about the time when the screen flickering issue started.
  3. Once you already have an app in mind, swipe down from the top of the screen to pull the notification panel down. 
  4. Tap the Settings icon on the upper-right corner. 
  5. Scroll to and then tap Apps. 
  6. Find and tap suspected app. 
  7. Tap Storage. 
  8. Touch Clear data and tap OK to confirm.
  9. Tap the back key once and then touch Uninstall. 
  10. Confirm that you want to remove the app from your phone. 

On the other hand, if the screen flickering issue continues even if the phone is in safe mode, then you must troubleshoot the firmware.

Third solution: Delete the system cache to fix screen flickering

Another possibility we have to look into is the chance that this problem is just caused by corrupt system cache. The cache gets corrupted or becomes obsolete from time to time especially when the firmware gets updated. When it happens, performance issues that also affect the hardware may occur and this problem could be just one of those cases. To rule this out, follow these steps: 

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Galaxy A50 logo shows, release all three keys.
  4. Your Galaxy A50 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step. 
  5. Press the Volume down key several times to highlight wipe cache partition.
  6. Press Power key to select.
  7. Press the Volume down key to highlight yes, them and press the Power key to select.
  8. When the wipe cache partition is complete, Reboot system now is highlighted.
  9. Press the Power key to restart the device.

Once the phone has successfully rebooted, try to see if the screen flickering is gone. If the problem continues, then you have no other choice but to do the next procedure.

Fourth solution: Backup your files and Master Reset your phone

If this is just one of the firmware issues that occur from time to time, a reset will fix it. It is very important that you reset your phone to know exactly if this is the kind of problem you can fix. If the screen flickering continues after the reset, then it’s probably an issue with the hardware. For that, you need to bring the phone to the Samsung Experience store so that a technician can check it for you. 

Before the reset, make sure to create a backup of your important files and data as they will be deleted. After the backup, remove your Google and Samsung accounts so that you won’t be locked out after the reset. Once everything is ready, follow these steps to reset your phone: 

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Galaxy A50 logo shows, release all three keys.
  4. Your Galaxy A50 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step. 
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

After this and the screen flickering issue continues, then send the phone in for tech repair or check up. But if the flickering is gone, then it was just a minor software-related problem and there’s nothing to worry about.
