Software-related flickering is usually intermittent and can often be resolved by updating or reinstalling software components.
Display Settings
Incorrect display settings, such as inappropriate screen brightness levels or refresh rates, can also lead to screen flickering. Some Android devices allow users to adjust the screen refresh rate, and setting it too high or too low might cause visual instability. Moreover, automatic brightness adjustments, also known as adaptive brightness, can sometimes cause the screen to flicker, especially under varying lighting conditions.
Battery and Power Issues
Battery or power supply problems can affect the phone’s ability to maintain a stable display. A weak or failing battery might struggle to provide consistent power to the display, leading to flickering. Additionally, issues with the power management system or charging components could also be contributing factors.
Hardware Defects
In some cases, screen flickering may result from hardware defects. A damaged or loose display connector, screen, or internal components can cause visual inconsistencies. Physical damage, such as drops or impacts, can also lead to hardware issues that manifest as screen flickering. Identifying hardware-related problems often requires a closer inspection or professional diagnosis.
By understanding these common causes, you can better diagnose the source of the screen flickering and apply appropriate solutions.
Initial Troubleshooting Steps
Before diving into more complex troubleshooting methods, it’s essential to start with some basic steps. These initial steps can often resolve the issue or at least provide more insight into the cause of the problem.
Restart Your Device
A simple restart can sometimes resolve screen flickering caused by temporary software glitches. Restarting the device refreshes the system and can clear minor errors. To restart your Android device, hold down the power button until the power menu appears, then select “Restart.” If the flickering stops after the reboot, the issue was likely due to a temporary software glitch.
Check for System and App Updates
Ensuring that your device’s operating system and applications are up to date can help resolve flickering caused by software bugs. Developers often release updates to fix known issues and improve stability. To check for updates, go to “Settings,” then “System,” and select “Software Update.” Similarly, visit the Google Play Store and check for app updates under “My apps & games.”
Adjust Display Settings
Review your display settings to ensure they are not causing the flickering. Start by turning off adaptive brightness (automatic brightness adjustment) to see if the flickering stops. You can do this by going to “Settings,” then “Display,” and disabling “Adaptive Brightness.” Additionally, if your device allows adjusting the screen refresh rate, try setting it to a different value and observe if the flickering persists.
Safe Mode
Booting your device into Safe Mode can help determine if the flickering is caused by a third-party app. In Safe Mode, your device only runs the essential system apps, disabling all third-party applications. To enter Safe Mode, press and hold the power button, then tap and hold “Power off” until the “Reboot to Safe Mode” option appears. If the screen flickering stops in Safe Mode, a third-party app is likely the culprit, and you can proceed to identify and uninstall the problematic app.
These initial troubleshooting steps can often resolve screen flickering issues or help you narrow down the cause for further diagnosis.
