Solutions for Fixing Screen Flickering

When troubleshooting disturbing screen flickering on your Galaxy F14, triaging the problem is key. Try these effective solutions:

Force restart your phone

Forcing your phone to restart can help to fix screen flickering issues because it can clear any temporary glitches or software conflicts that may be causing the problem. It also refreshes the operating system and all of the apps running on your device.

To force restart your Galaxy F14, press and hold the volume down button and the power button simultaneously for at least 7 seconds. Your phone will then restart automatically.

Force restarting your phone is a safe and effective way to troubleshoot a variety of problems, including screen flickering. It is also a good first step to take before trying any other troubleshooting solutions.

Close apps running in the background

Closing apps running in the background can help to fix screen flickering issues because it can free up system resources and reduce the workload on your phone’s processor. This can help to improve the overall performance of your phone and prevent any glitches or software conflicts that may be causing the screen to flicker.

In addition, some apps may continue to run in the background even after you close them. These apps can continue to use system resources and battery power, even if you are not actively using them. This can put additional strain on your phone’s processor and graphics card, which can lead to screen flickering.

To close apps running in the background on your Galaxy F14, follow these steps:

1. Tap the Recent key.

2. Tap Close all.

You can also close all of the apps running in the background at once by tapping the Close all button at the top of the Recent apps screen.

Closing apps running in the background is a good practice to follow on a regular basis, even if you are not experiencing any problems. It can help to improve the performance of your phone and extend the battery life.

Update the Software and Apps

Updating your software and apps is important for a number of reasons, including:

• Security: Software updates often include security patches that can help to protect your device from known vulnerabilities. This is especially important for operating system updates, but it is also important to keep your apps up to date.
• Performance: Software updates can also include performance improvements that can make your device run faster and more smoothly. This is especially important for games and other demanding apps.
• New features: Software updates can also add new features to your device. For example, a recent update to the Android operating system added a new feature that allows you to take screenshots by swiping down with three fingers.
• Compatibility: Software updates can also help to ensure compatibility with other devices and services. For example, if you are using an older version of an app, it may not work properly with the latest version of the operating system.

To update your software and apps on your Galaxy F14, follow these steps:

1. Open the Settings app, and tap on Software update.

2. Tap on Download and install.

If there is an update available, your phone will download and install it automatically.

To update your apps, follow these steps:

1. Open the Play Store, and tap on your Profile picture.

2. Tap on Manage apps & device, then tap Manage.

3. Tap Updates available, and update the apps that need updating.

You can also set your apps to update automatically by following these steps:

1. Open the Google Play Store app.
2. Tap on the Menu button (three horizontal lines).
3. Tap on Settings.
4. Tap on Auto-update apps.
5. Select the option that you want: Over Wi-Fi only or Over any network.

It is important to note that some software updates may require you to restart your device. Be sure to save any important work before installing an update.

Toggle Adaptive Brightness On and Off

Adaptive brightness is a feature that automatically adjusts the brightness of your phone’s screen based on the ambient light level. This can help to save battery life and improve the visibility of the screen in different lighting conditions.

However, adaptive brightness can sometimes cause screen flickering issues. This is because the feature may be constantly adjusting the brightness of the screen, even if the ambient light level is not changing significantly. This can lead to a flickering effect, especially in low-light conditions.

To fix this issue, you can try toggling adaptive brightness on and off. This will reset the feature and may help to resolve any flickering problems.

To toggle adaptive brightness on and off on your Galaxy F14, follow these steps:

1. Open the Settings app.

2. Tap on Display, then tap on the switch next to Adaptive brightness.

If you are still experiencing screen flickering issues after toggling adaptive brightness on and off, you can try other troubleshooting solutions, such as updating your software and apps, closing apps running in the background, or running your phone in safe mode.

Here are some other reasons why you might want to toggle adaptive brightness on and off:

• If you are finding that the screen is too bright or too dim, you can toggle adaptive brightness off and adjust the brightness manually.
• If you are using your phone in low-light conditions, you may want to toggle adaptive brightness off to prevent the screen from flickering.
• If you are using a screen protector, you may want to toggle adaptive brightness off to improve the visibility of the screen.

Run in Safe Mode

Running your Galaxy F14 in safe mode can help you to troubleshoot screen flickering issues because it starts your phone with the default settings and only the essential apps running. This means that any third-party apps that may be causing the flickering problem will be temporarily disabled.

To run your Galaxy F14 in safe mode:

1. Press and hold the power button until the power off menu appears.
2. Tap and hold the Power off option until it turns into Safe mode.
3. Tap Safe mode to restart your phone in safe mode.

To exit safe mode:

1. Press and hold the power button until the power off menu appears.
2. Tap Restart.

If the screen flickering stops when you run your phone in safe mode, this means that a third-party app is likely the culprit. To identify the specific app that is causing the problem, you can start by enabling your third-party apps one by one and seeing if the flickering returns. Once you have identified the problem app, you can uninstall it or disable it.

If the screen flickering continues even when you run your phone in safe mode, this means that the problem is likely caused by a software or hardware issue with your phone itself. In this case, you may need to contact Samsung support for further assistance.

Check for Physical Damage

You need to check for physical damage when troubleshooting screen flickering issues because physical damage to the phone’s display or cables can disrupt the visual signal and cause flickering.

Here are some common types of physical damage that can cause screen flickering:

• Drops: If your phone has been dropped, it is possible that the display has been damaged. This can cause the screen to flicker or even go black completely.
• Water damage: If your phone has been exposed to water, it is possible that the display has been damaged. This can also cause the screen to flicker or go black.
• Cracked display: If the phone’s display is cracked, it is possible that the cracks are interfering with the visual signal. This can cause the screen to flicker or even go black.
• Loose or damaged cables: If the cables that connect the display to the phone’s motherboard are loose or damaged, this can also cause the screen to flicker.

If you suspect that your phone’s screen flickering is caused by physical damage, you should take it to a qualified repair technician to have it inspected.

Here are some tips for checking for physical damage to your phone’s display:

• Look for any cracks or chips in the display.
• Press on the display gently to see if you can feel any loose or damaged pixels.
• Try to turn on the phone in a dark room and see if you can see any light leaking from the display.
• If you see any of these signs of physical damage, it is likely that your phone’s screen flickering is caused by the damage.

If you are not comfortable checking for physical damage yourself, you can take your phone to a qualified repair technician to have it inspected.

Try a Different Charging Cable

You need to try a different charging cable when troubleshooting screen flickering issues because a bad charging cable can provide inconsistent power to the display processor, inducing flickering.

The charging cable is responsible for delivering power from the charger to the phone. If the cable is damaged or faulty, it can cause the phone to receive inconsistent power. This can lead to a variety of problems, including screen flickering.

Here are some signs that your charging cable may be faulty:

• The cable is frayed or damaged.
• The cable is not properly connecting to the charger or phone.
• The cable is overheating.
• The cable is not charging the phone properly.

If you are experiencing screen flickering issues, try using a different charging cable to see if that resolves the problem. If you do not have another charging cable available, you can try restarting your phone or running it in safe mode. If the screen flickering continues even after restarting your phone in safe mode, then the problem is likely caused by a software or hardware issue with your phone itself. In this case, you may need to contact Samsung support for further assistance.

Here are some tips for choosing a good charging cable:

• Choose a cable that is certified by the manufacturer of your phone.
• Avoid using cheap or generic cables.
• Inspect the cable regularly for signs of wear and tear.
• Replace the cable immediately if it is damaged.

By following these tips, you can help to prevent screen flickering issues caused by faulty charging cables.

Back Up Data and Factory Reset

You need to back up your data and factory reset your phone when troubleshooting screen flickering issues because a factory reset can erase any lingering software bugs that could be causing the problem.

A factory reset is a process that restores your phone to its factory default settings. This means that all of your data, apps, and settings will be erased. However, a factory reset can also fix a variety of problems, including screen flickering.

Before you perform a factory reset, it is important to back up all of your data. You can do this by using a cloud storage service, such as Google Drive or iCloud, or by connecting your phone to a computer and transferring the files.

Once you have backed up your data, you can perform a factory reset by following these steps:

1. Open the Settings app, then tap General management.
2. Tap Reset, and select Factory data reset.
3. Tap on the Reset button, and tap Delete all.
4. Enter your password and proceed with the reset.

Your phone will then restart and begin the factory reset process. This may take a few minutes.

Once the factory reset is complete, your phone will be restored to its factory default settings. You will need to set up your phone again and install any apps that you want to use.

If you are still experiencing screen flickering issues after performing a factory reset, then the problem is likely caused by a hardware issue with your phone itself. In this case, you may need to contact Samsung support for further assistance.

With focus and persistence, you can uncover the specific trigger for your Galaxy F14’s screen flickering.
