The screen of the Galaxy Tab S7 is flickering – an unpleasant situation that may arise for no apparent reason. But, such a problem can be very serious. Especially if it started after physical damage to your device.

However, it may also just be one of those little firmware-related issues. The screen flicker problem may be a sign of a hardware or software problem.  Let’s look into this issue.

The screen of the Galaxy Tab S7 flickers

If it’s a hardware problem, it’s best to check your device. Another thing is if the screen started flickering for no apparent reason. It’s probably just a minor software issue.

Let’s consider the first solution to the problem. First, close the background applications and force restart the Samsung Galaxy Tab S7 tablet. Now check if the fault has been fixed.



To force restart the tablet, press and hold the power button and the volume down button for 10 seconds. This will turn off the tablet and turn it on again. A brief description of the solutions to the problem:

• Check the screen settings: Go to the device settings and select the “Screen” section. Make sure that you are using the recommended screen settings and that the “Auto Brightness” feature is enabled.
• Clear the cache and application data: If the problem occurs only when using a specific application, try to clear the cache and data of this application. To do this, go to Settings > Applications > select Application > Storage > Clear Data and Clear Cache.
• Check for updates: Make sure your device is running on the latest version of the operating system and all applications. To do this, go to “Settings” > “Software Update” and select “Update”.
• Try restarting your device: Sometimes a simple restart of the device can help fix problems with the screen.

Starting in safe mode

The second solution: start the device in safe mode. To find out if installed applications are causing this problem, you need to start the tablet in safe mode. This will temporarily disable all third-party applications.

If any of them causes flickering, the problem should not occur while the device is in safe mode. To activate the mode, you need to do the following:

• Swipe down from the top of the screen and tap the power icon.
• Press and hold the power off option until it switches to safe mode.
• Tap “Safe Mode” to restart the tablet.

In safe mode, try to check if the Galaxy screen is flickering or not. If the problem is resolved, find the apps causing the problem and uninstall them. However, if the problem persists, proceed to the next solution.

Galaxy Tab S7 Update

Third solution: Check for new updates. Firmware-related problems are often solved with an update. Perhaps Samsung has already released a new firmware update that can solve this problem.

So, follow these steps:

• Launch the Settings app.
• Scroll down and click Software Update.
• Click “Download and Install” to check for new updates.

After updating the tablet, check if the cause has been eliminated. If the screen of the Galaxy S7 256gb continues to flicker, then we try next.

Resetting the device to factory settings

Resetting to factory settings may solve the problem if it is not a hardware cause. Before doing this, take some time to back up important files and data, as they will be deleted.

When you’re done, follow these steps to restart your tablet:

• Open the Settings app on your tablet.
• Scroll down and tap “General Management”.
• Tap Reset.
