The Samsung S21 Ultra is an amazing phone with a beautiful screen and strong performance. Just like any electronic gadget, it might have issues with its screen that can make people unhappy. We will explore some common Samsung S21 Ultra screen issues and provide practical solutions to fix them. Whether you’re dealing with display glitches, touchscreen problems, or other screen-related issues, we’ve got you covered.

1. Screen Flickering or Blinking

Screen flickering or blinking is a frustrating problem that can disrupt your viewing experience. This problem can happen because of problems with the computer programs or when they don’t work well together. To fix it:


  • Restart your Samsung S21 Ultra.
  • Check if there are any new updates for the software, and if there are, go ahead and install them.
  • Try something called “Safe Mode” to see if any apps you added are causing the problem. If the issue disappears in Safe Mode, consider removing apps you recently added.
  • If the problem continues, you can consider doing a factory reset as a final choice. But remember to save your data somewhere else before doing this.

2. Unresponsive Touch Screen

An unresponsive touch screen can render your device nearly unusable. The problem might be due to software troubles, screen protector issues, or problems with the device’s hardware.


  • Remove any screen protectors or cases and test the touchscreen responsiveness.
  • Make sure your screen is clean and doesn’t have any dirt or oily marks that might make it hard to touch.
  •  Look for software updates and put them on your device.
  • If the problem persists, seek professional help to diagnose and repair any hardware issues.

3. Screen Burn-In

Screen burn-in occurs when static images or elements become permanently visible on the display. It’s a common issue with OLED screens like the one on the Samsung S21 Ultra.


  • Use the “Screen Saver” feature or set a shorter screen timeout to minimize static images.
  • Avoid displaying the same static content for extended periods.
  • Consider using apps that can help mitigate screen burn-in by shifting pixels slightly.

4. Ghost Touches or Phantom Inputs

Ghost touches are when the screen registers touches or swipes without any user interaction. Sometimes, the screen can have problems because of different things, like issues with the software or the phone’s parts.


  • Clean your screen to ensure there are no dirt or moisture particles causing false touches.
  • Restart your device to see if the issue persists.
  • Check for software updates and install them.

If the issue keeps going, get help from an expert to check and fix any hardware problems.

5. Screen Freezing or Lag

Screen freezing or lag can be incredibly frustrating, especially when trying to navigate or use apps smoothly.


  • Restart your Samsung S21 Ultra to clear temporary glitches.
  • Clear app cache and data for apps that are causing the lag.
  • Make sure your device has enough storage space and isn’t running too many apps at the same time.

If the problem doesn’t go away, you might want to think about doing a factory reset. Just be sure to save your data before you do it.

6. Dead Pixels

Dead pixels are tiny parts of the screen that don’t show any colors or content. They can be bothersome and make your overall viewing less enjoyable.


Dead pixels are primarily a hardware issue.

  • If your Samsung S21 Ultra is still covered by the warranty, get in touch with the company that made it or an authorized repair center.
  • Explore repair or replacement options with warranty coverage.
  • Don’t try to repair dead pixels on your own, as trying to do it yourself might make the problem worse and harm your device.

7. Battery Drain Due to Screen

Excessive battery drain attributed to screen usage can disrupt your device’s performance and daily usage.

  • Optimize screen settings by reducing screen timeout and adjusting brightness to conserve battery power.
  • Turn on battery-saving modes when needed to limit background activities and make your battery last longer.
  • Be mindful of apps running in the background and close or force-stop them when not in use to prevent unnecessary battery drain.
  • If your device’s battery is degraded and no longer holds a charge efficiently, consult a professional technician or authorized service center for a battery replacement.
