Experiencing a flickering phone screen during calls can be incredibly frustrating and disruptive to your communication. This issue might stem from various causes, including software glitches, hardware problems, or environmental factors. Luckily, many of these issues can be resolved with some straightforward troubleshooting steps. In this guide, we'll explore effective methods to fix your phone screen flickering during calls, helping you restore smooth and clear communication without unnecessary interruptions.
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 your device refreshes the system and closes any background apps that might be interfering with the display.
- Press and hold the power button until the restart options appear.
- Select "Restart" or "Reboot."
- Wait for the device to reboot and test if the flickering persists.
2. Check for Software Updates
Outdated software can cause compatibility issues that lead to display problems. Ensuring your device runs the latest software version can fix bugs and improve performance.
- Navigate to Settings > Software Update (or System > Updates).
- Download and install any available updates.
- After updating, restart your device and check if the flickering continues.
3. Adjust Screen Brightness and Auto-Brightness Settings
In some cases, fluctuating brightness settings can cause the screen to flicker during calls. Disabling auto-brightness and manually adjusting the brightness might stabilize the display.
- Go to Settings > Display > Brightness.
- Turn off "Auto-Brightness" or "Adaptive Brightness."
- Set a fixed brightness level and observe if the flickering stops.
4. Clear Cache and App Data
Corrupted cache files or app data can interfere with phone functions, including the display during calls. Clearing cache can often resolve these issues.
- Go to Settings > Apps & Notifications > See All Apps.
- Select the Phone app or Dialer app.
- Tap on Storage & Cache.
- Choose "Clear Cache" and, if necessary, "Clear Data."
- Restart your device and test the calls again.
5. Check for Hardware Issues
If software troubleshooting doesn't resolve the flickering, the problem might be hardware-related. Common hardware issues include loose connections or damaged display components.
- Inspect the screen for physical damage, cracks, or discoloration.
- If the device has been dropped or exposed to water, internal damage could be causing flickering.
- Consider visiting a professional repair center for a hardware diagnosis and repair.
6. Disable Hardware Overlays and Developer Options
Enabling developer options and hardware overlays can sometimes cause display issues. Disabling hardware overlays can help stabilize the screen during calls.
- Go to Settings > About Phone and tap "Build Number" seven times to enable Developer Options.
- Navigate to Settings > Developer Options.
- Scroll down to "Hardware Layers" or "Disable HW Overlays" and enable this option.
- Restart your device and check if flickering persists.
7. Reset Network Settings
Network-related issues can sometimes cause display problems during calls. Resetting network settings can resolve conflicts that might lead to screen flickering.
- Go to Settings > System > Reset Options.
- Select "Reset Wi-Fi, Mobile & Bluetooth."
- Confirm and allow the device to reset network settings.
- Reconnect to your networks and test calling functionality.
8. Factory Reset as a Last Resort
If none of the above solutions work, performing a factory reset might be necessary. This will erase all data on your device, so ensure you back up important information beforehand.
- Go to Settings > System > Reset > Factory Data Reset.
- Follow the prompts to reset your device to factory settings.
- Set up your device anew and check if the flickering issue is resolved.
Conclusion: Key Points to Remember
Dealing with a flickering phone screen during calls can be frustrating, but most issues are fixable with simple troubleshooting steps. Start with basic solutions like restarting your device, updating software, and adjusting display settings. If problems persist, check for hardware damage or consider professional repair. Resetting network settings or performing a factory reset can also help resolve stubborn issues. By systematically addressing potential causes, you can restore your phone's display stability and enjoy clear, uninterrupted calls once again. Remember to back up important data before performing major resets, and don’t hesitate to seek professional assistance if hardware problems are suspected.
