First solution: Reboot your phone (soft reset).
If this is just the first time for your phone screen to act weird, then it’s probably just a random glitch on any of your apps, if not the phone’s operating system. A highly recommended simple solution to random software glitches including those that are depicted by screen flickering symptom is a soft reset or reboot on your device. Aside from fixing minor software errors, a soft reset also clears up some space of the internal memory. This then results to a smoother and a faster performance. And here’s how it’s done:
- To soft reset or restart your Galaxy A6 2018, you can just press the Power button until the menu appears and then tap the option to Power Off. After 30 seconds, you can press the Power button again until the device restarts.
- Alternatively, you can just press and hold the Power button and the Volume Down button on the side until the phone restarts.
A soft reset does not affect any data stored on the internal memory of your device. That said, you don’t need to create backups.
Second solution: Force close/quit all background apps.
Background apps are comprised of apps you’ve recently used and haven’t closed. While keeping apps running in the background offers benefit when it comes to multitasking as you can just switch between apps previews, time will come that any these apps would crash or failed to start. When this happens, there is a higher chance for other apps or even the phone system’s operation to become affected. As a result, your device would tend to misbehave and the flickering display you’re dealing with could be the transpiring symptom. To rule this out, force all background apps to quit with these steps:
- Launch the Recent Apps menu on your phone. A list of recently used apps will then show up.
- Navigate to an app then swipe up to close.
- Do the same to the rest of the background apps.
Reboot your Galaxy A6 (2018) when you’re done closing all background apps. Doing so will refresh your phone’s internal memory and operating system as well.
Third solution: Boot into safe mode and diagnose apps.
To make sure that the screen flickering problem on your Galaxy A6 (2018) is not inflicted by any of your third-party apps or downloaded contents, try to boot your phone in safe mode. All third-party applications are temporary disabled or not permitted to run while in safe mode, thus it would be easier for you to determine whether a third-party app is to blame or not. Here’s how to enable safe mode on your Galaxy A6 (2018) smartphone:
- Press and hold the Power button until the phone vibrates and the Samsung logo appears then release the Power button.
- With the Samsung Galaxy logo still on screen, press the Volume Down button.
- Keep holding the Volume Down button until Safe Mode appears in the lower-left corner of the Home screen or lock screen.
- You can release the Volume button by then.
If the screen does not flicker while running in safe mode, then it’s safe to say the problem is caused by a third-party app. It could be the most recent app or content you’ve downloaded on your phone. At this point, you can try uninstalling apps individually until the problem is fixed.
Fourth solution: Update apps and phone software to the latest version available.
Software updates can be the key to fixing the screen flickering problem on your Galaxy A6 (2018), especially if it’s caused by some bugs or malware. Aside from bringing in new features, updates also embed security patches to get rid of any existing bugs and malware that caused various types of software issues in certain Galaxy devices. Aside from software updates, installing app updates might also help especially if it has something to do with a third-party app that’s not compatible with the current platform or operating system your phone is running on.
Here’s how to manually check for available app updates on your Galaxy A6 (2018):
- Make sure your phone is connected to Wi-Fi Internet.
- Go to Play Store and then click Menu.
- Tap on My Apps & Games.
- Tap to update apps individually.
- Tap on the Update button.
Follow the onscreen instructions to complete the app updates installation and then reboot your device when done.
To check for software (Android) update available for your device, head over to Settings-> About device -> Software update -> Update now or Settings -> Software update -> Download updates manually.
Again, make sure that your phone is connected to the Internet. Or you can also update your phone on a computer. Don’t forget to reboot or soft reset your device when the update is finished, to make sure all recent changes brought by the new system update are properly implemented.
Fifth solution: Reset your Galaxy A6 (2018) to its factory default settings.
As last resort, you may reset your device to its factory settings and then set it up as new. This would be necessary if the problem is caused by some serious bugs or malware that might have inflicted complex errors on the phone system. A factory reset or master reset wipes everything from your device including your personal data, customized settings, downloaded apps and other contents along with any tough bugs. Should you wish to continue with this reset, be sure to back up all your important data, so you can recover and use them again later. Once you’re all set, you can proceed with these steps:
- With your device powered off, press and hold the Power, Home and Volume Up buttons simultaneously for a few seconds.
- Release the buttons when the Android screen appears and the phone loads in Recovery mode.
- Press the Volume Down button to highlight Wipe data/Factory reset option.
- Then press the Power button to confirm selection.
- When the factory data reset is finished, the Reboot System Now option is highlighted. Press the Power button to confirm and reboot your device to apply the recent changes and refresh the operating system.
Wait for your device to complete the system reset and then restarts by itself. When it’s booted up completely, you can proceed with the initial setup process.
Any of the aforementioned procedures should be able to fix software-related screen flickering problem on your Galaxy A6 (2018) smartphone unless physical or liquid damage exists. That said, your last be hope to get your phone display working properly again is through tech service or repair. If your device is still under warranty, then don’t forget to avail for service warranty or unit replacement. Contact your carrier or Samsung Support for more information on how to avail for warranty and request further assistance on what to do next.
