Experiencing a flashing or flickering phone screen during calls can be incredibly frustrating and disruptive. This issue not only affects your viewing experience but can also interfere with your ability to communicate effectively. Fortunately, many cases of screen flashing are fixable with straightforward troubleshooting steps. In this guide, we’ll explore the common causes of this problem and provide practical solutions to help you restore your phone’s display to normal during calls.

How to Fix Phone Screen Flashing During Calls

1. Restart Your Phone

Sometimes, a simple restart can resolve temporary glitches that cause screen flickering. Restarting your device refreshes the system and clears minor software hiccups.

  • Hold down the power button until the restart option appears.
  • Select “Restart” or “Reboot.”
  • Allow the device to fully reboot and check if the screen flickering persists.

If the problem continues, proceed to other troubleshooting methods.

2. Check for Software Updates

Outdated software can cause compatibility issues, including screen flickering during calls. Keeping your device updated ensures you have the latest fixes and improvements.

  • Go to your phone’s Settings.
  • Scroll to “Software Update” or “System Updates.”
  • Download and install any available updates.
  • Restart your device after updating and test the call function again.

3. Clear Cache Partition (Android Devices)

Corrupted cache files can cause display issues. Clearing the cache partition can help eliminate such glitches without deleting personal data.

  • Power off your device.
  • Boot into recovery mode (the method varies by device model).
  • Use volume buttons to navigate to “Wipe Cache Partition.”
  • Select it with the power button.
  • Reboot the device and check if the problem is resolved.

4. Check for App Conflicts

Third-party apps can sometimes interfere with system functions, including the display during calls.

  • Boot your phone in Safe Mode (usually by holding the power button and selecting “Safe Mode”).
  • Make a call to see if the screen flickering persists.
  • If the issue stops in Safe Mode, an app may be the culprit.
  • Identify and uninstall recently installed or updated apps that might be causing conflicts.
  • Restart your device normally and test again.

5. Adjust Screen Refresh Rate Settings

Some devices allow users to modify the screen refresh rate, which can impact flickering issues.

  • Go to Settings > Display > Screen Refresh Rate (or similar).
  • Set it to a standard rate (e.g., 60Hz).
  • Test during calls to see if flickering is resolved.

6. Disable Hardware Overlays (Android Devices)

Hardware overlays can sometimes cause display problems. Disabling them can improve stability.

  • Enable Developer Options by going to Settings > About Phone > Tap “Build Number” seven times.
  • Return to Settings > Developer Options.
  • Find “Disable HW overlays” and toggle it on.
  • Restart your device and observe whether the flickering persists.

7. Check for Physical Damage or Loose Connections

If your phone has been dropped or exposed to water, hardware damage could be causing the flickering.

  • Inspect the screen for cracks or discoloration.
  • Gently press around the edges of the screen to detect loose connections.
  • If you suspect hardware damage, consult a professional technician for repair.

8. Reset to Factory Settings

If all other steps fail, performing a factory reset can eliminate software issues that might be causing the flickering. Remember to back up your data before proceeding.

  • Go to Settings > System > Reset options.
  • Select “Erase all data” or “Factory reset.”
  • Follow on-screen instructions to complete the reset.
  • Set up your device anew and test during calls.

9. Seek Professional Repair

If the problem persists after trying all software solutions, it might be a hardware issue requiring professional attention. Contact your device manufacturer or an authorized service center for diagnosis and repair.

Conclusion: Key Takeaways for Fixing Screen Flickering During Calls

Screen flashing during calls can stem from a variety of causes, including software glitches, app conflicts, display settings, or hardware damage. To effectively address this issue, start with simple solutions like restarting your device, updating software, and clearing cache. If these don’t work, delve into more specific adjustments such as Safe Mode testing, display settings modifications, or hardware inspections. In cases where hardware damage is suspected, professional repair services are the safest option. By systematically troubleshooting these areas, you can restore your phone’s display stability and enjoy clear, flicker-free calls once again.
