Experiencing a flickering phone screen during calls can be both frustrating and disruptive, affecting your ability to communicate effectively. This common issue may stem from various hardware or software problems, and understanding the cause is the first step toward resolving it. Whether your device is new or old, there are multiple troubleshooting methods you can try to fix the flickering and restore a clear, stable display during calls.
How to Fix Phone Screen Flickering During Calls
1. Restart Your Phone
Sometimes, a simple restart can resolve temporary glitches causing the screen flickering. Restarting clears the device’s cache and resets temporary settings that might be interfering with the display.
- Press and hold the power button until options appear.
- Select “Restart” or “Reboot.”
- Wait for the device to restart and check if the issue persists.
2. Check and Update Your Software
Software bugs are a common cause of display issues. Ensuring your phone’s operating system and apps are up to date can often fix bugs contributing to flickering during calls.
- Go to Settings > Software Update (or System Updates).
- Download and install any available updates.
- After updating, test the screen during a call to see if the problem is resolved.
3. Adjust Screen Brightness and Settings
Automatic brightness or adaptive display features can sometimes cause flickering, especially during calls when ambient light changes. Disabling or adjusting these settings might help.
- Navigate to Settings > Display.
- Turn off “Auto Brightness” or “Adaptive Brightness.”
- Adjust brightness manually to a comfortable level.
- Test during a call if flickering continues.
4. Check for Hardware Issues
Physical damage or loose connections can lead to screen flickering. Inspect your device for signs of damage like cracks or water ingress. If you suspect hardware failure:
- Seek professional repair services or visit an authorized service center.
- Consider replacing the screen if it is damaged.
Note: Avoid attempting hardware repairs yourself unless you are experienced, as it may void warranties or cause further damage.
5. Disable Hardware Overlays and Developer Options
Enabling developer options and certain hardware overlays can cause display issues. Turning these off may help stabilize your screen during calls.
- Enable Developer Options by going to Settings > About Phone > Tap Build Number 7 times.
- Return to Settings > Developer Options.
- Scroll to “Drawing” or similar section and disable options like “Hardware Layers Updates.”
After adjustments, test your phone during calls to see if flickering persists.
6. Reset App Preferences and Clear Cache
Corrupted app data can interfere with the display, especially if a third-party app is involved. Resetting app preferences and clearing cache can help.
- Go to Settings > Apps > Menu (three dots) > Reset app preferences.
- Clear cache for the Phone app and any other relevant apps:
- Settings > Apps > [App Name] > Storage > Clear Cache.
- Restart your device and check if the flickering continues.
7. Test in Safe Mode
Booting your device in Safe Mode disables third-party apps, helping identify if an app is causing the flickering during calls.
- Press and hold the power button.
- Tap and hold “Power Off” until the option for Safe Mode appears, then confirm.
- Use your phone normally during a call to see if the flickering occurs.
- If the issue stops, consider uninstalling recently added apps.
- Exit Safe Mode by restarting your device.
8. Factory Reset as a Last Resort
If all other methods fail, performing a factory reset can resolve deep software issues causing flickering. Be sure to back up important data before proceeding.
- Go to Settings > System > Reset > Factory Data Reset.
- Follow on-screen instructions to reset your device.
- Set up your phone anew and test during calls.
Note: Factory resetting will erase all data, so back up photos, contacts, and other essential information beforehand.
9. Seek Professional Assistance
If none of the above solutions work, the problem might be hardware-related, such as a faulty display connector or other internal components. Contact your device manufacturer or an authorized repair center for expert diagnosis and repair.
Additional Tips to Prevent Screen Flickering During Calls
- Use a protective case that doesn’t put pressure on the screen or internal components.
- Avoid exposing your phone to extreme temperatures or moisture.
- Keep your device updated regularly to prevent software-related glitches.
- Avoid installing untrusted apps that may interfere with system stability.
Summary: How to Fix Phone Screen Flickering During Calls
Experiencing screen flickering during calls can often be resolved with simple troubleshooting steps. Start by restarting your device and updating your software to eliminate temporary bugs. Adjusting display settings and disabling features like auto-brightness can help stabilize the screen. Checking for hardware damage and performing software resets or booting in safe mode can identify underlying issues. If the problem persists, professional repair may be necessary, especially if hardware components are faulty. Regular maintenance, updates, and cautious handling can prevent future flickering problems, ensuring your phone remains reliable during every call.
