Troubleshooting Screen Flickering and Shading on Samsung Galaxy S7

Screen flickering and shading on your Samsung Galaxy S7 can be a frustrating experience. However, while a failing battery can contribute to these performance issues, it is not the only potential cause. This article aims to help you understand the various factors that might be causing the problem and provide steps to troubleshoot it effectively.

Common Causes of Screen Flickering and Shading on Samsung Galaxy S7

When experiencing screen flickering and shading on your Samsung Galaxy S7, display issues, software glitches, battery health, overheating, and settings or accessibility features are all potential causes to consider. Here are some detailed steps you can take to diagnose and potentially resolve the issue:

Display Issues

The screen itself might have hardware problems, such as a loose connection or physical damage. In these cases, it is best to ensure the physical integrity of the device.

Software Glitches

Software bugs or outdated apps can cause display issues. Make sure your operating system and all your apps are up to date. This can be done through the 'Software Update' section of the device's settings.

Battery Health

A failing battery can lead to inconsistent power delivery, which might cause the screen to flicker. Swollen batteries or batteries showing signs of damage are no longer safe and should be replaced. Use a reliable battery health app to assess the condition of your battery.

Overheating

If your phone is overheating, it can also cause display problems. Check for apps that are overworking the CPU or for any other issues that might be causing excessive heat. This can be done by monitoring temperature levels in the device settings or using third-party apps like 'CPU Cooler' or 'Battery Doctor'.

Settings and Accessibility Features

Incorrectly configured settings or accessibility features might inadvertently cause display issues. Ensure that your display settings are configured correctly. This can usually be found under the 'Display' or 'Settings > Display' section of the device's settings.

Next Steps for Troubleshooting

Here are some specific steps you can take to help resolve screen flickering and shading on your Samsung Galaxy S7:

Restart the Device: Sometimes a simple restart can resolve temporary software issues. Swipe down from the top of the screen to bring up the notification panel, then swipe up again to restart your device. Safe Mode: Boot the phone in Safe Mode to see if the problem persists. To do this, cut the power to your device, then hold down the Power button, and immediately hold down the Volume Down button. If the issue does not persist in Safe Mode, a third-party app may be the culprit, which can be identified by enabling Safe Mode and reinstalling the apps one by one. Check Battery Health: Use a reputable battery health app to assess the condition of your battery. This can help identify if the battery is the cause of the issue. Professional Help: If the problem continues, consider taking the phone to a professional repair service to diagnose and fix the issue.

If the battery is indeed failing, replacing it may resolve some of the flickering issues. However, it is essential to identify the root cause first. Exploring the potential causes above will help you determine if the issue is related to the display, software, battery, overheating, or settings.

Additional Considerations

It is important to note that the screen issues you are experiencing might not be strictly related to the LCD. The absence of a traditional backlight in smartphone displays means that the issue can be attributed to an unregulated amount of power, which could be due to the battery or a power management chip. It can be challenging to diagnose the exact cause.

Do You Mean Flicker or Restart Issues?

If you are experiencing flickering, it is likely caused by issues with power delivery, which can be battery-related or due to the screen itself. If your phone restarts often and you are experiencing flickering issues, it might be unrelated, and further investigation is needed. When under warranty, it is recommended to have the device checked at an official service center.
