How to Fix a Samsung Screen That Keeps Flickering and Dimming

Having a new or old Samsung device with a flickering screen can be annoying because it interrupts the usual functionality. You think at first that it’s a single problem that will go away after a while, but it lasts longer than you thought. The flickering screen problems started after the Samsung Galaxy came out. People have been complaining about the screen flickering since then. 

First, make sure your apps are up-to-date, then turn off third-party apps and hardware overlays. Next, make sure the proximity sensor works, then turn off adaptive brightness and increase the timeout on the screen. Finally, ensure the screen timeout setting is set, choose the secure lock settings for how long it stays on and turn off power-saving mode. If flickering continues, do a hard reset on your phone or tablet.

Why Is My Samsung Screen Flickering, Dimming?

What causes the screen to flicker? A possible reason for the flickering screen is a problem in the brightness settings. The auto-brightness setting is the most common problem. As a rule, the option is used to automatically adjust screen brightness depending on data from the light sensors on the screen.

Screen flickering is also caused by bad hardware and software problems, like installing an app that needs a high screen resolution to run. 

Another possible cause is having too many apps open at once, or app crashes. This usually causes the screen to freeze especially if the device does not have enough storage space.

Tips for fixing the problem if your Samsung screen is flickering and dimming

  • Make sure your apps are up-to-date.
  • Turn off third-party apps.
  • Turn off hardware overlays. 
  • Make sure the proximity sensor works.
  • Turn off adaptive brightness.
  • Increase the timeout on the screen.
  • The screen timeout setting is set.
  • Secure lock settings.
  • Make sure that the power-saving mode is turned off.

Do you know how to get rid of a flickering screen?

To get rid of screen flickers, here are a few tips and tricks that you can try:

1. Make sure your apps are up-to-date.

Before you think about what kind of Samsung phone or tablet repair services you need, make sure that all of your apps are up-to-date.

Go to the Google Play Store and click on “My Apps.” You will see new updates there. Ensure your Android system is updated, not just the apps. 

Go to “Settings,” then select “About Phone.” If your software is out of date, you’ll see it. So use caution when you try this simple and easy hack. Try the next step if it does not fix the dimming.

2. Turn off third-party apps.

If a third-party app is causing screen flickering, you can disable it to solve the problem. To get rid of third-party apps, you need to start your phone in Safe Mode. For most Samsung phones, the process is about the same. 

Here’s how to do it:

  • Turn the phone off, press the power button and hold it. If you see the Samsung logo, let go of it.
  • Press and hold power button and volume down button right away. Keep it there until your phone starts up again.
  • Safe mode should appear on the bottom left of your screen. The chances are that one of the third-party apps on your phone is to blame for your screen flickering.
  • Find recently installed apps and find the one that started flickering simultaneously.

It’s time to get rid of the apps causing problems android. First, take a look at the settings on your phone. Click “Apps” to see all the apps that you have. Tap on the app that isn’t working. Then go to storage, clear its data and cache, and tap on the app again.

If your screen is still flickering even after resetting the app, uninstall it to solve the problem.

3. Turn off the hardware overlays.

If the flickering happens when your device’s screen is set to low brightness, turning off hardware overlays might help. 

  • Select “Settings” on your phone. Then, go to the System tab, then “About Device.” 
  • Press “Build Number” until your screen says, “You’re a developer now.”
  • Go back to “Settings,” tap “System,” and click on “Developer Options,” then you can change the settings. 
  • When you get to the “Rendering Section” or “Drawing Section,” click on “Turn off Hardware Overlays” to turn them off.

When you’re done with the cache partition, you should wipe it clean. You can wipe the cache partition in “Recovery Mode.” This is another way to fix Samsung screen glitches. Doing this clears the cache on your phone.

To get rid of the cache:

  • Turn off your phone: Press and hold the Home, Volume Up, and Power buttons together until the Android logo shows up. The Bixby button can be used instead of the Home button on a Galaxy S8 because there isn’t one on that phone.
  • Recovery mode should appear at this point, and you should choose it from the menu. 
  • Make sure the process is completed by pressing the Power button. Wait for the process to finish.
  • Select “Reboot System Now” by moving through the menu with the Volume Up button and then selecting the Power button. If you do this, your phone will restart like you usually do.

After the computer restarts, it should fix the glitch on the screen. If not, move on to the next.

4. Make sure the proximity sensor works.

A proximity sensor on your phone tells you when it is close to your face, so you don’t accidentally touch the options when you are on the phone. Keep an eye on your screen to ensure that a case or cover isn’t blocking the proximity sensor.

5. Turn off adaptive brightness.

To control the brightness of your screen, you might want to turn off the Adaptive brightness feature and just set the brightness yourself.

  • Select “Settings.”
  • Select the “Display” button and press it to show.
  • Tap the switch to turn off “Adaptive brightness.”
  • Slide bar to the right to make the screen brighter.

6. Increase the timeout on the screen.

It will turn off the screen after a certain amount of time. For example, if it’s set for 15 seconds, it may look like the screen is turning off too soon. This is because the timer is set to 15 seconds. From 15 seconds to 10 minutes, you can change the amount of time it takes to finish the task.

Here’s how to do it:

  • Select “settings”
  • Select the “Display” button and press it to show.
  • Select “Screen Time Out.”
  • Select how long you want the screen to stay on.
  • Keep the screen on as you work with it.

7. The screen timeout setting is set.

Samsung Galaxy phones feature the front camera to figure out when to dim the screen or turn off the screen. If the screen timeout setting is set, it will stay on even if your face is on the screen.

The steps below show how to do them on devices that are running Android 10. However, you may have to take a different route to get to the Smart Stay menu on older phones.

Here’s how to do it:

  • Select “Settings.”
  • Select the “Advanced features” button.
  • Select “Motions and gestures.”
  • Turn on “Keep screen on while viewing.”

8. Secure lock settings.

The Secure lock settings let you change how secure your lock screen is. It’s not the only setting you can change. You can also choose how long your device stays unlocked after the screen turns off by itself. You can select a delay time from right away to 30 minutes.

Here’s how to do it:

  • Select “Settings.”
  • Then, press “Lock screen.”
  • Select “Secure lock settings,” then enter your PIN, pattern, or password.
  • Turn on “Auto-lock when the screen goes off.”
  • Change the time delay.

9. Make sure that the power-saving mode is turned off.

It helps the battery last longer by disabling features that use battery power. This could change how long the screen stays on. From the quick panel, you can turn on and off Power Savings.

10. Do a hard reset on your phone or tablet.

You can do this by hard resetting your phone. Unfortunately, this will delete everything on your phone, including your settings and any data you have saved. So, it should be your last chance to fix a flickering screen.

You must back up your data on your Samsung account before you do this, so you don’t lose any of it.

  • Recovering mode is the way to start your phone when it doesn’t work.
  • From the menu that appears, choose the “Factory Reset/Wipe Data” option. 
  • Press the power button to confirm your choice.
  • When the hard reset process is done, your phone will restart itself.

What if the Screen Flickering Problem Doesn’t Go Away?

If all of the above did not stop the flickering screen, the problem is most likely hardware-related. In this case, DIY fixes aren’t the best idea. Instead, you’ll need to go to a good phone repair shop to get it fixed.

How to fix Samsung laptop with a flickering screen?

Few computer problems are more annoying or difficult to fix than a flickering screen. It used to be common for people to use Cathode Ray Tube (CRT) monitors. CRTs are much more sensitive than LED screens, as anyone who has worked with a CRT will tell you.

That doesn’t mean that flickering can’t happen to a flat-screen TV: There are a lot of the same things that make your screen flicker. Some problems, like electromagnetic interference, have already been solved. But these tips for how to fix a Samsung laptop with a flickering screen should help.

Make sure the cables are good.

In this case, it doesn’t matter if you’re using a VGA, HDMI, DVI, or DisplayPort cable. However, if the cable isn’t properly connected, there will be problems.

It’s important to check the cable on both the computer and the screen. First, make sure it is tightened down or plugged back in. If that doesn’t work, try to buy a new cable. If that doesn’t work, it’s time to look into something else.

Check the refresh rate of the screen.

The number of times the screen image changes in a second, as measured in Hertz. Flickering, lag, and other things can happen if the refresh rate isn’t correct or too low.

Here’s how to do it:

  • To check the refresh rate on a Windows 10 computer, press the Windows key, type “refresh rate” into the search field, and then click on “View Advanced Display.”
  • Now, click on the Properties button for the display adapter for Display 1. (or whichever number display is causing the issue).
  • In the properties window, click the middle tab called “Monitor.” You’ll see a place where you can set the refresh rate.

If you don’t know what it should be set to, check your monitor’s manufacturer’s website. You should be able to find out the best refresh rate for your model.

Check your video card.

There are a lot of problems that can happen if a video card isn’t correctly attached to the motherboard. One of them is that the screen flickers. Turn off the computer and look inside the case to see if anything is missing. It’s important to find the video card and check if it’s connected properly.

It’s most likely that the card isn’t working if it’s in the right place on your motherboard. This is easy to do, especially if the computer you want to test has a built-in GPU that you can plug into.

Here’s how to do it:

  • Remove the video card from the computer.
  • Turn the computer off.
  • Connect your monitor cable to the onboard card or another video card.
  • Turn the computer back on. 

If the problem doesn’t go away, then the problem isn’t the card—something else.

Check out the screen.

Invariably, the monitor could be bad. But, before you throw it away, there are a few things you should do. 

Here’s how to do it:

  • First, check the monitor to see if it’s broken or if any settings might be causing the problem.
  • Check to see if everything looks good. 
  • Then, unplug the old one and get the new one. 

If the new monitor works well, you’ve found your problem. 


There is no quick fix for Samsung screen flickering. Instead, you can follow this step-by-step guide to help solve the problem. If the problem persists, contact Samsung customer support or visit a local Samsung repair shop near you.
