Why Does My Galaxy S24 Ultra Screen Flicker?
- Software conflicts: Recent app installations or software updates might have introduced bugs leading to flickering.
- Display settings: Settings like adaptive brightness or high refresh rates can sometimes interfere with the display, especially if incompatible with an app.
- Overheating: Excessive heat can affect the display components, causing temporary flickering.
- Hardware problems: In rarer cases, the issue can be caused by a loose display connector or damaged screen component.
1. Restart your device
A simple restart can often fix temporary software glitches. This allows your phone to reinitialize and potentially clear up the screen flickering issue.
- Press and hold the power and volume down buttons.
- Select Restart.
2. Check for app updates
Outdated apps may be conflicting with your phone’s system software or display settings. Updating them ensures compatibility and potential bug fixes.
- Open the Google Play Store app.
- Tap your profile icon in the top right.
- Tap Manage apps & device.
- Tap Updates available and select Update all.
3. Disable adaptive brightness
Adaptive brightness automatically adjusts screen brightness based on ambient light, but it can sometimes cause flickering. Disabling it can help stabilize the display.
- Go to Settings.
- Tap Display.
- Toggle off Adaptive brightness.
4. Adjust screen refresh rate
High refresh rates offer smoother visuals, but they can also put more strain on the display components. Lowering the refresh rate might alleviate flickering.
- Go to Settings.
- Tap Display.
- Select Motion smoothness.
- Choose Standard instead of Adaptive.
5. Check for software updates
Samsung regularly releases software updates with bug fixes and optimizations. Updating your phone might resolve display-related problems.
- Go to Settings.
- Tap Software update.
- Tap Download and install.
6. Boot into Safe Mode
Safe Mode disables third-party apps, helping you determine if a third-party app is causing the flickering. If the problem disappears in Safe Mode, a recently installed app is likely the culprit.
- Press and hold the power button.
- Tap and hold the Power off icon until the Safe Mode prompt appears.
- Tap Safe Mode.
7. Disable hardware overlays in Developer Options
Disabling hardware overlays forces your phone to use the GPU for all screen rendering. This could help if the screen flickering is caused by a software conflict.
- Go to Settings.
- Tap About phone.
- Tap Software information.
- Tap Build number seven times quickly.
- Go back to Settings and tap Developer options.
- Find Disable HW overlays or Force GPU rendering and enable it.
8. Change screen mode (e.g., Vivid to Natural)
Different screen modes have specific color profiles, and some can be more prone to flickering. Switching to a more natural color mode may be helpful.
- Go to Settings.
- Tap Display.
- Select Screen mode and choose Natural.
9. Perform a screen calibration (if the option is available)
Some Samsung devices may allow manual screen calibration. This can help fine-tune the display settings to reduce potential flickering.
- Go to Settings.
- Search for “screen calibration” (Note: this option may not be available on all S24 Ultra models).
- Follow the on-screen instructions to adjust colors and white balance.
10. Adjust screen timeout settings
A shorter screen timeout will turn off the display more quickly when idle. This can reduce strain on the display components and potentially mitigate flickering.
- Go to Settings.
- Tap Display.
- Tap Screen timeout and select a shorter duration.
11. Disable eye comfort shield
Eye comfort shield or blue light filters can alter screen colors and sometimes cause interference. Disabling them temporarily can help identify if they contribute to the flickering.
- Go to Settings.
- Tap Display.
- Toggle off Eye comfort shield
12. Factory reset your phone
This is a last resort if other solutions fail. A factory reset will erase all data and restore your phone to default settings, clearing out any potential software issues. Make sure to back up your data beforehand.
- Go to Settings.
- Tap General management.
- Tap Reset.
- Select Factory data reset and follow the instructions.
13. Contact Samsung Support
If none of the above solutions work, the issue may be hardware-related. Contact Samsung Support or visit an authorized repair center for diagnosis and potential repair or replacement.
