Samsung Screen Flickering? Causes and How to Fix It 

1. What Causes Samsung Screen Flickering?

Flickering can come from several different sources, and identifying the pattern helps narrow down the cause:

• Software-related flicker — happens in specific apps or after updates, often tied to refresh rate or brightness settings
• Hardware-related flicker — happens consistently regardless of app, often after a drop or exposure to water
• Adaptive brightness conflicts — the screen rapidly adjusts brightness in changing light, which can look like flickering
• Loose display connector — common after a drop, causing intermittent flicker that worsens with pressure on the phone

Pay attention to when the flickering happens. If it only occurs in one app, it’s almost certainly software. If it happens everywhere, including on the lock screen, hardware becomes more likely.

2. Restart Your Phone First

Before diving into settings, a simple restart resolves a surprising number of display glitches by clearing temporary system processes.

How to restart:

1. Press and hold the Power and Volume Down buttons
2. Select Restart
3. Check if the flickering continues once the phone boots back up

If the flicker disappears immediately after restarting but returns after a while, that points toward a background app or a memory issue rather than a hardware fault.

3. Turn Off Adaptive Brightness

Adaptive brightness constantly adjusts your screen based on ambient light, and in certain lighting conditions, this adjustment can look like flickering.

How to disable it:

1. Go to Settings
2. Tap Display
3. Turn off Adaptive brightness
4. Manually set your preferred brightness level

If the flickering stops, you’ve found your cause. You can turn Adaptive brightness back on later and see if the issue returns, which helps confirm the connection.

4. Adjust or Disable Motion Smoothness (Refresh Rate)

On Galaxy phones with high refresh rate displays, an unstable connection between the refresh rate and certain apps can cause visible flicker, especially during scrolling or animations.

How to change it:

1. Go to Settings > Display
2. Tap Motion smoothness
3. Switch from Adaptive or 120Hz to Standard (60Hz)

Use your phone normally for a day. If the flickering stops on 60Hz, the issue is tied to how a specific app or your display handles the higher refresh rate, and you may want to keep it on Standard until an app update resolves the conflict.

5. Check for Software Updates

Display bugs are among the most common issues Samsung addresses in One UI updates, particularly after a major Android version upgrade.

Steps to update:

1. Go to Settings
2. Tap Software update
3. Tap Download and install

Also check for updates to any apps where you notice flickering specifically. Game and video apps in particular sometimes ship updates with display bugs that get patched within days.

6. Boot Into Safe Mode to Test for App Conflicts

If flickering happens in specific apps or randomly throughout the day, a third-party app could be the cause, particularly ones that use overlays, custom themes, or screen filters.

How to boot into Safe Mode:

1. Press and hold the Power button
2. Press and hold Power off in the menu that appears
3. Tap Safe mode and confirm

Safe Mode temporarily disables all third-party apps. If the screen doesn’t flicker in Safe Mode, an installed app is the cause. Reboot normally and uninstall recently added apps one at a time, starting with anything related to themes, launchers, or screen dimmers.

7. Check for Overheating

Excessive heat can cause temporary display glitches, including flickering, especially during heavy gaming, extended camera use, or fast charging in warm environments.

What to do:

• Remove the phone case to allow better heat dissipation
• Avoid using the phone while it’s fast charging in direct sunlight
• Let the phone cool down for 15–20 minutes and check if the flickering stops

If overheating is the cause, the flickering should disappear once the phone returns to a normal temperature.

8. Inspect for Physical Damage

If your Galaxy phone has been dropped, exposed to water, or squeezed in a tight pocket recently, a loose display connector or damaged panel is a likely explanation, especially if flickering worsens when you press gently on the edges of the screen.

Signs pointing to hardware damage:

• Flickering appears immediately after a drop or impact
• The screen flickers more when the phone is bent slightly or pressed
• Visible cracks, discoloration, or dead pixels accompany the flicker
• The issue persists in Safe Mode and after a factory reset

If any of these apply, this isn’t a software problem, and continuing to use the phone risks making the damage worse. It’s best to have the display inspected by a professional. If the phone is older or the repair cost is close to the value of the device, it may be worth reading about how to prepare your device for resale before deciding between a repair and an upgrade.

Conclusion

Samsung screen flickering is unsettling, but it’s rarely a sign your phone is beyond saving. Start with the simple checks — a restart, adaptive brightness, and refresh rate settings — before moving on to Safe Mode and software updates. If the flickering only shows up after a drop or continues even in Safe Mode, it’s time to get the display professionally inspected rather than risk further damage. With the right diagnosis, most flickering issues are a quick fix, not a phone replacement.
