Samsung Screen Flickering? 8 Fixes That Actually Work

 

You pick up your Samsung phone to check a message, and the screen flickers. You ignore it. It happens again while watching a video. Then again while scrolling. Now it won't stop.

Sound familiar?

Screen flickering is one of the most reported display problems among Samsung users — and one of the most frustrating. You didn't drop your phone. You didn't get it wet. It just started doing this on its own.

The good news? Most of the time, it is not a hardware problem. It is a software issue, and software issues can be fixed right from your settings — no technician, no repair shop, no money spent.

In this article, I will walk you through 8 fixes for Samsung screen flickering, starting from the easiest and working up to the more advanced. Try them in order, and you will likely solve the problem before you even reach Fix 5.

What Causes Samsung Screen Flickering?

Before we fix it, let's understand it. Your Samsung screen can flicker for several reasons:

Software causes (most common):

  • Adaptive brightness reading light conditions incorrectly
  • A third-party app interfering with the display driver
  • Corrupted cache files after an update
Hardware causes (less common):
  • A loose display flex cable (more common in foldable phones)
  • Physical damage to the screen
  • Aging display panel

The fixes below target software causes first — because that is what most users are dealing with. If you go through all 8 fixes and the flickering continues, the last section will tell you what to do next.

Fix 1: 

Restart Your Phone

It sounds too simple. But a restart clears temporary glitches in the system that can cause display issues, and it takes less than a minute.

How to restart:

  • Press and hold the Power button
  • Tap Restart
  • Wait for the phone to fully reboot

Once it restarts, use your phone normally for a few minutes and see if the flickering comes back. If it does, move to Fix 2.

Fix 2: 

Turn Off Adaptive Brightness

This is the most common fix for Samsung screen flickering — and for good reason. Adaptive brightness uses your phone's light sensor to automatically adjust screen brightness based on your environment. When this sensor glitches, the screen can flicker rapidly as the brightness keeps adjusting up and down.

Turning it off is quick and often solves the problem immediately.

How to turn off Adaptive Brightness:

  • Open Settings
  • Tap Display
  • Find Adaptive brightness and toggle it OFF
  • Manually adjust your brightness to a comfortable level

Check if the flickering has stopped. Many users find this single fix solves everything.

Fix 3: 

Change Motion Smoothness to Standard

Samsung phones with 120Hz displays use a feature called Motion Smoothness that dynamically switches the refresh rate between 60Hz and 120Hz depending on what you are doing. This switching can sometimes cause visible screen flickering, especially on certain firmware versions.

Changing the setting to Standard locks the refresh rate at 60Hz and removes the switching — which often eliminates the flicker.

How to change Motion Smoothness:

  • Open Settings
  • Tap Display
  • Tap Motion smoothness
  • Select Standard (instead of Adaptive)
  • Tap Apply

Note:

 This option is only available on Samsung phones with 120Hz displays, such as the Galaxy S and Galaxy A series mid-range and above.

Fix 4: 

Check for a Software Update

Samsung regularly releases software updates that include bug fixes for display issues. If your screen started flickering after a recent update, there may already be a patch available. If it flickered before any update, an update might still be the fix.

How to check for updates:

  • Open Settings
  • Scroll down and tap Software update
  • Tap Download and install
  • If an update is available, install it and restart your phone

Always keep your Samsung updated. Regular updates also bring new features — read our article on Samsung hidden features you probably did not know about. Most display bugs get fixed within a few weeks of being reported.

Fix 5: 

Boot in Safe Mode to Find a Bad App

Safe Mode starts your Samsung phone using only its core system apps. All third-party apps you downloaded are temporarily disabled. This is one of the smartest diagnostic tools available to you.

If the flickering stops in Safe Mode, a third-party app is causing it. If it continues, the problem is in the system itself.

How to enter Safe Mode:

  • Press and hold the Power button
  • Tap and hold the Power off icon on your screen
  • When the Safe mode prompt appears, tap it
  • Your phone will restart and you will see "Safe mode" written at the bottom of the screen

Use your phone for a few minutes in Safe Mode.

Flickering stopped? A downloaded app is the culprit. Exit Safe Mode (restart normally) and uninstall apps you recently added, one by one, until the flickering stops.

Flickering continues? The problem is not an app — move to Fix 6.

To exit Safe Mode: Simply restart your phone normally.

Fix 6: 

Clear App Cache

Every app on your phone stores temporary files called cache to help it load faster. Over time — especially after a software update — these cached files can become outdated or corrupted, and they can interfere with how your display performs.

Clearing the cache does not delete your personal data, photos, or app settings. It just removes the temporary files so they can be rebuilt fresh.

How to clear cache for a specific app:

  • Open Settings
  • Tap Apps
  • Select the app you suspect is causing the issue
  • Tap Storage
  • Tap Clear cache

If you are not sure which app is causing it, repeat this for recently installed or updated apps. Clearing cache regularly also helps your battery last longer — see  our Samsung battery tips article.

Fix 7: 

Wipe the Cache Partition

This is different from clearing an individual app's cache. Wiping the cache partition clears the system-level temporary files stored on your phone. This is especially useful when flickering started after a major software update.

Important: 

This does not delete your personal files, photos, contacts, or apps.

How to wipe cache partition on Samsung:

  • Turn off your phone by pressing Power + Volume Down, then tap Power off
  • Connect your phone to a computer using a USB cable
  • Press and hold Volume Up + Power button together until the Samsung logo appears
  • Release the buttons when you see the Android recovery screen
  • Use the Volume buttons to navigate to Wipe cache partition
  • Press the Power button to select it
  • Confirm and wait for the process to complete
  • Select Reboot system now

This process looks a little technical but it is safe and straightforward. Many users find this fixes flickering that nothing else could solve.

Fix 8: 

Factory Reset (Last Resort)

If you have tried all the fixes above and the screen is still flickering, a factory reset will restore your phone to its original settings — as if it just came out of the box. This eliminates any software conflict, corrupted file, or bad setting that may be causing the problem.

Warning:

 A factory reset deletes everything on your phone. Back up your photos, contacts, and important files before doing this.

How to back up your data:

  • Go to Settings > Accounts and backup > Back up data
  • Or back up to Google Drive or Samsung Cloud

How to factory reset:

  • Open Settings
  • Tap General management
  • Tap Reset
  • Tap Factory data reset
  • Read the warning, then tap Reset
  • Enter your PIN if asked, then confirm

Your phone will restart and set itself up fresh. If the flickering is gone after the reset, the problem was definitely software. If it is still there — it is time to visit a service center.

When to Visit Samsung Service Center

You have tried everything. The screen is still flickering. At this point, the problem is most likely hardware — and that needs a professional.

Go to a Samsung Service Center if:

  • The flickering continues after a factory reset
  • You can see physical damage, cracks, or black spots on the screen
  • The flickering is getting worse over time
  • Your phone got wet or was dropped recently

You can find your nearest Samsung Service Center at samsung.com/support or through the Samsung Members app on your phone. If your phone is still under warranty, the repair may be free.

Frequently Asked Questions

Q. 1: Why is my Samsung screen flickering randomly?

Most likely it is Adaptive Brightness reacting incorrectly to light changes. Go to Settings > Display and turn it off — this fixes the problem for most users.

Q. 2: Does Samsung screen flickering mean my phone is damaged?

Not necessarily. Most flickering is a software issue, not physical damage. Hardware is only a concern if your phone was dropped, got wet, or nothing fixes the flickering.

Q.3: Can a software update cause screen flickering?

Yes. Some updates leave behind corrupted cache files that cause flickering. Wiping the cache partition usually solves it without deleting your personal data.

Q.4: Why does my Samsung screen flicker at low brightness? 

Samsung OLED screens use PWM at low brightness, which some people see as flickering. Try increasing brightness slightly or turning on Eye Comfort Shield.

Q.5: Will Safe Mode fix my Samsung screen flickering?

Safe Mode does not fix it, but it tells you if an app is causing it. If flickering stops in Safe Mode, uninstall your recently downloaded apps one by one.

Q.6: Does factory reset fix screen flickering on Samsung?

Yes, if the cause is a software conflict. It is a last resort — always back up your data before doing a factory reset.

Q.7: My Samsung screen flickers only while charging — is that normal?

 A third-party or damaged charger can interfere with the display. Try your original Samsung charger and see if the flickering stops.

Conclusion

A flickering Samsung screen is annoying, but it is almost always fixable at home. In most cases, simply turning off Adaptive Brightness or changing Motion Smoothness to Standard solves the problem within minutes. If those do not work, a software update or Safe Mode check will usually get to the bottom of it.

Only consider a factory reset if everything else has failed — and if the flickering survives even that, then it is a hardware issue and time to visit a Samsung Service Center.

The important thing is to stay calm and go through the fixes one by one. You do not need a technician for this. Most Samsung users solve it on their own.

How to Increase FPS on Android and Mobile Games (No Root Needed)

You're mid-match, everything's on the line — and your game chugs. The screen stutters, your character lags a half-second behind your thumb, and just like that, the round's gone. Sound familiar? Low FPS is one of the most common complaints Android gamers deal with, and the frustrating part is most people assume they need a new phone to fix it. They don't. A few small changes — no root required — can make your games run noticeably smoother. What Even Is FPS? FPS means "frames per second." The higher the number, the smoother your game looks and feels. Most games run best at 60 FPS. If your phone is dropping below that, things start to look like a slideshow — and that's frustrating, especially mid-match. 1. Turn On Game Mode (If Your Phone Has It) Many Android phones — like Samsung, Xiaomi, Realme, and others — come with a built-in Game Mode or Game Booster. Go to your Settings and search for "Game Mode" or "Game Booster." Turn it on. It bl...

Android Privacy Settings You Need to Change Right Now (2026)

Image
You unlock your phone, and somewhere in the background, an old flashlight app you installed two years ago is quietly checking your microphone permissions. You'd never notice — most people don't. That's the uncomfortable truth about Android privacy in 2026: your phone knows far more about you than you realize, and most of that access was granted by accident, not intention. It's not just paranoia. Location history, voice activity, camera access, contact lists — a surprising number of apps request permissions they don't actually need to function. The good news is Android has gotten much better at giving you visibility and control, if you know where to look. If you've ever wanted to keep certain apps private from prying eyes too, our guide on how to hide apps on Android pairs well with these privacy settings. 1 .

It stays fully installed and working — it just disappears from view. Let's go through the four easiest ways to do it, whether you're on Samsung , Xiaomi , or stock Android.
