Samsung Galaxy S23 Ultra Display Issues and How to Fix Them

The Samsung Galaxy S23 Ultra is one of the most powerful smartphones on the market, known for its stunning 6.8″ Dynamic AMOLED 2X display, ultra-sharp resolution, and smooth performance. However, even top-tier phones can face display-related problems over time. Whether due to software glitches, accidental damage, or hardware defects, it’s important to identify the cause and apply the right solution.

Common Display Issues with the Galaxy S23 Ultra

1. Screen Flickering

Some users have reported flickering or flashing on the screen, especially in low brightness settings or during multitasking.

How to Fix:

Go to Settings > Display > Eye comfort shield and turn it off.
Disable Adaptive Brightness.
If the issue persists, boot the phone in Safe Mode to check if third-party apps are causing the problem.
Software updates may fix this issue—keep your phone updated.

2. Green or Pink Line on Display

This issue may appear suddenly and could be linked to screen pressure, drops, or even software updates.

How to Fix:

Try restarting your phone or performing a soft reset.
If it’s software-related, a future firmware update might resolve it.
If the line remains, it’s likely a hardware defect and needs professional display replacement.

3. Touchscreen Not Responding Properly

Unresponsive areas on the screen or delayed touch response can interfere with regular usage.

How to Fix:

Remove any screen protector or case that may be affecting touch sensitivity.
Increase touch sensitivity: Settings > Display > Touch sensitivity.
If the issue continues, back up your data and perform a factory reset.

4. Dead Pixels or Black Spots

Dead pixels or black dots may appear due to pressure, heat, or impact damage.

How to Fix:

Minor dead pixels sometimes fix themselves. Use a pixel-fixer app to stimulate the area.
For persistent dead pixels or screen burn-in, professional repair or screen replacement is required.

When to Visit a Repair Shop
