How To Fix The Galaxy Tab S7 Screen Flickering Issue

In this troubleshooting guide, we will show you how you can fix the Galaxy Tab S7 screen flickering issue that seems to be bugging some users. Such a problem can be pretty serious, especially if it started after your device has incurred some physical damage. But it can also be just one of those pretty minor, firmware-related issues. Read on to learn more about it. 

The screen flickering problem can be a sign of either a hardware or software issue. If it’s a problem with the hardware, then the best thing you can do is to have your device checked. However, if it occurred without apparent reason or cause, then it’s probably just a minor software-related problem. Needless to say, you can fix it by doing some basic troubleshooting. With that being said, here’s what you should do about it: 

First solution: Close background apps and force restart your tablet

There is a possibility that the screen flickers due to some CPU-intensive apps that are left running in the background. So the first thing you have to do is to close them, and then refresh your tablet’s memory, as well as reload all its apps and services. Here’s how you do that: 

  1. Tap the Recent Apps key to view apps running in the background. 
  2. Tap Close All to force quit the apps. 
  3. To force restart your tablet, press and hold the Power key and the Volume Down button for 10 seconds. This will trigger your device to shut down and power back up. 
  4. When the logo shows, release both keys and allow your tablet to continue the boot process. 

After doing that, try to see if your device’s screen still flickers. 

Second solution: Run your device in Safe mode

Another thing you need to do to find out if the apps you installed are causing this problem, is to run your tablet in safe mode. Doing so will temporarily disable all third-party applications. So if one of them causes the flickering, the problem shouldn’t occur while the device is in that mode. Here’s how it’s done: 

  1. Swipe down from the top of the screen, and tap the Power icon. 
  2. Tap and hold on the Power off option until it turns into Safe mode. 
  3. Tap Safe mode to restart your tablet. 

Once in safe mode, try to see if your tablet’s screen still flickers. If the problem is fixed, then look for the apps that are causing the problem and uninstall them. However, if the issue remains, then move on to the next solution. 

Third solution: Check for new update

After doing the first two solutions and the screen still flickers, then the next thing you have to do is to check for a new update. Firmware-related issues are often fixed through an update. Perhaps Samsung already rolled out a new firmware update that can fix this problem. So follow these steps: 

  1. Launch the Settings app. 
  2. Scroll down and tap Software update. 
  3. Tap Download and Install to check for new updates. 

After updating your tablet and the problem continues, then move on to the next solution. 

Fourth solution: Reset all the settings on your tablet

If you’ve changed some settings on your device prior to this problem, then it’s possible that the screen flickering is just due to some inappropriate settings. So the next thing you have to do is to reset all the settings on your tablet. Here’s how you do that: 

  1. Open the Settings app on your tablet. 
  2. Scroll down and tap General management. 
  3. Tap Reset. 
  4. Tap Reset settings. 
  5. Tap the Reset settings button, and enter your security lock. 
  6. Now tap the Reset button to proceed with the settings reset. 

After the settings reset, observe your device to see if the screen still flickers. 

Fifth solution: Wipe the cache partition

Once you’re done resetting the settings on your Galaxy Tab S7 and the screen continues to flicker, then the next thing you have to do is to delete the system cache, because it’s possible that it’s corrupted and causes some of the features to crash or not work properly. So wipe the cache partition so that it will be replaced. Here’s how: 

  1. Turn off your tablet completely. 
  2. After it slightly vibrates, press and hold the Power key and the Volume Up button. 
  3. Once the logo shows, release both keys and wait until your device enters the Recovery Mode. 
  4. Now press the Volume Down button a few times to highlight ‘wipe cache partition,’ and then press the Power key to select. 
  5. Highlight Yes using the Volume Down key and press the Power key to select it. 
  6. Once your tablet has finished clearing the cache partition, press the Power key to reboot it. 

After the restart, try to see if the problem is fixed. 

Sixth solution: Factory reset your device

After doing the previous procedures and your Galaxy Tab S7 still has the screen flickering issue, you have no other choice but to reset it. A factory reset will be able to fix it as long as it’s not a hardware issue. But before you do that, take a little time backing up your important files and data as they will be deleted. Once you’re ready, follow these steps to reset your tablet. 

  1. Open the Settings app on your tablet. 
  2. Scroll down and tap General management. 
  3. Tap Reset. 
  4. Tap Factory data reset. 
  5. Scroll down and tap the Reset button. 
  6. If prompted, enter your security lock. 
  7. Tap Delete all. 
  8. Enter your Samsung account password, and tap Done to proceed with Factory reset. 

Once the reset is finished, set up your tablet as a new device. If for some reason the issue continues after the factory reset, then that’s the time to bring it to the shop so that a technician can take a look at it. 

And that’s what you need to do to fix the Galaxy Tab S7 screen flickering problem. We hope that this simple tutorial can help you one way or another.
