Fix Screen Flickering on Samsung Galaxy After Update

If your Samsung Galaxy screen starts flickering after a recent software update, don’t panic — it’s usually a software-related issue that can be fixed easily. Follow these steps to restore smooth display performance.

Step 1: Restart Your Galaxy

Start with a simple restart. Press and hold the Power button, then tap Restart. This clears minor cache glitches caused by the update.

Step 2: Check Adaptive Brightness

Go to Settings > Display and toggle Adaptive Brightness off. Some firmware versions can cause flickering when brightness adjusts automatically under certain lighting conditions.

Step 3: Disable Eye Comfort Shield or Extra Dim

In Settings > Display, temporarily turn off Eye Comfort Shield and Extra Dim. These modes can sometimes interfere with display calibration after updates.

Step 4: Boot into Safe Mode

Press and hold the Power button, then touch and hold Power off > Safe mode. This disables third-party apps — if flickering stops, an app may be the culprit. Uninstall recently updated apps to test.

Step 5: Adjust Refresh Rate

Navigate to Settings > Display > Motion Smoothness and choose Standard (60Hz). Some Galaxy models flicker under Adaptive (120Hz) right after an update until firmware stabilizes.

Step 6: Update or Reinstall Display Drivers

Head to Settings > Software Update and install the latest patches. If the problem persists, wipe the cache partition in Recovery Mode — this often resolves post-update display issues.

OnePlus Tip

If the issue persists even after software updates, back up your data and perform a Factory Reset. This clears leftover cache and conflicting settings from previous firmware versions that can trigger flickering.
