Samsung Galaxy Note 9 screen starts to flicker after the Android 9.0 Pie update

Screen flickering issues can either be due to a minor firmware problem or a serious hardware issue involving the display itself. Some owners of the Samsung Galaxy Note 9 reported that shortly after they updated their phones to Android 9.0 Pie, the screen started to flicker. Assuming that there’s no sign of physical or liquid damage, it’s most likely due to a software-related issue.

So, in this post, I will walk you through in troubleshooting your Note 9 with a screen flickering issue. If you’re one of the owners of this device and are currently being bugged by a similar problem, continue reading as this article may be able to help you one way or another.

Now, before anything else, if you have other issues with your phone, make sure you drop by our troubleshooting page for we have already provided solutions to hundreds of problems reported by our readers. Odds are that we may have already provided a solution to the problem you currently have so try to find issues that are similar with yours on that page and feel free to use the solutions we suggested. If they don’t work or if you need further assistance, fill up our Android issues questionnaire and hit submit to contact us.

The following are things you can do if your Galaxy Note 9 has a screen flickering issue after the Android Pie update…

  1. Run your phone in Safe Mode and continue using it.
  2. Uninstall third-party apps that may be causing the problem.
  3. Wipe cache partition to delete and replace old system cache.
  4. Factory reset your phone.

You have already rebooted your phone many times but if still not, then try that and see if that improves your phone’s performance or get rid of the flickering. If not,then try running your device in safe mode to temporarily disable all third-party applications. There are times when third-party apps cause the screen to flicker especially CPU- and GPU-intensive ones. This is how you restart your Note 9 in safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen appearing on the screen.
  3. When SAMSUNG appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. When Safe mode appears in the bottom left corner of the screen, release the Volume down key.

Assuming the screen flickering issue doesn’t occur in this mode, the next thing you have to do is find out which of your apps is causing the problem and uninstall it. That should take care of the problem.

However, if the issue continues even in safe mode, then you have to delete the old system cache so that it will replaced with a new one. You can do so by running your phone in recovery mode and wiping the cache partition. Android will automatically create a new cache for the new firmware. Here’s how it’s done:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Android logo displays, release all three keys.
  4. An ‘Installing system update’ message will show for 30 – 60 seconds before the Android system recovery menu options appear.
  5. Press the Volume down key several times to highlight wipe cache partition.
  6. Press Power key to select.
  7. Press the Volume down key to highlight yes, them and press the Power key to select.
  8. When the wipe cache partition is complete, Reboot system now is highlighted.
  9. Press the Power key to restart the device.

It will take a little while for your phone to boot up as the cache is being rebuilt. Once it becomes active, try to see if the flickering continues and if so, then you have to backup your files and data and then factory reset  your phone. It’s necessary at this point to rule out the possibility that it’s just a firmware-related concern. So, take time moving your important files over to your SD card, computer or to the cloud. After that, remove your Google account from your phone and then follow these steps to reset your device:

  1. Back up data on the internal memory. If you have signed into a Samsung account on the device, you have activated Anti-theft and will need your Samsung credentials to finish the master reset.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

If the problem continues after the reset, bring your phone to the shop so the technician can check it for you.

How to fix screen flickering issue on your Samsung Galaxy Note 8 (easy steps)

Display issues in mobile devices like screen flickering can be attributed to software errors or hardware damage. The latter could be the underlying cause if there were previous instances of hard falls or liquid exposure on the device. But if the screen flickering problem suddenly occurs, then it could be due to a system malfunction. Bad apps, faulty update, and incorrect display settings are usually among the common triggers for software-related display errors. Considering that the problem is tied to software errors, there are a few workarounds you can try on to troubleshoot and fix it on your end. The methods I’ve highlighted below can be utilized when dealing with screen flickering problem on a particular Samsung handset, which is the Galaxy Note 8. Feel free to refer to these workarounds whenever you need more help in fixing the annoying flickering display.

Before going further, if you found this post because you were trying to find a solution to your problem, then try to visit our Galaxy Note 8 troubleshooting page as we’ve already addressed most of the commonly reported issues with the phone. We’ve already provided solutions to some of the problems reported by our readers so try to find issues that are similar with yours and use the solutions we suggested. If they don’t work for you and if you need further assistance, fill up our Android issues questionnaire and hit submit.

First solution: Restart your phone.

For first instances, your phone screen may be flickering because of random software glitches. And in that case, the issue can potentially be resolved by restarting your device or soft reset. This should clear any minor software errors that might have caused your display to suddenly act oddly. A soft reset or device restart can be done in two way depending on what state your device is. If your phone is still able to respond properly, you can do the usual restart with these steps:

  1. Press and hold the Power button for a few seconds until the Power off prompt appears.
  2. Tap the Restart option.
  3. Tap Restart again to confirm.
  4. Give your phone up to 90 seconds to complete the restart process.

Meanwhile, if your phone is frozen or not responding, you can perform a soft reset using the hardware keys instead. And here’s how it’s done:

  1. Press and hold the Power button and Volume Down button simultaneously for up to 45 seconds.
  2. Release both buttons when the phone power cycles.

No data will be deleted from either methods so there’s no need for backups.

Second solution: Quit all background apps.

Background apps can go rogue when they crash and when this happens, certain functions including display rendering may also become affected or stopped working as intended. Although it offers an advantage to keep your apps running in the background especially for multitasking purposes, there are times when you really have to quit them. To make sure that none of your background apps is trigger your display to flicker at some point, force them to close with these steps:

  1. Press the Recent apps key located on the bottom left corner of the screen. Doing so will show up a list of your recently used apps.
  2. To close an individual app, tap the app from the list and drag it to the left or right. Alternatively, you can just tap the X.
  3. To close all recent apps at once, tap the option to Clear All instead.

After clearing all background apps, restart your phone to apply  the new changes and to refresh the phone’s internal memory.

Third solution: Manage display settings.

Some people who have encountered a similar issue in which their Galaxy Note 8 screen starts to flicker have found out that screen brightness has something to do with it. Others have it that the screen would flicker if the display is set to too high while others at some other level. To make sure this is not causing your phone to act the same, try to manage the display settings and adjust the screen brightness. Here’s how to access and manage display settings, particularly screen brightness on your Samsung Galaxy Note 8:

  1. Open the notification panel by dragging the status bar downwards.
  2. Next, drag the notification panel downwards.
  3. Then tap the arrow next to the brightness adjustment bar.
  4. If you want to show the controls on top, tap the switch to Show Control on top.
  5. Tap Done when you’re finished modifying display settings.

Restart your phone then see if that fixes the flickering display.

Fourth solution: Boot your phone into safe mode.

If configuring the screen brightness settings doesn’t help, you can proceed with diagnosing apps. Some third-party apps can be the culprit especially when they get corrupted or contain some malware that might have ruined your phone’s screen functions. Booting in safe mode will disable all third-party apps so it would be easier for you to determine if the screen flickering problem is isolated to a downloaded app or not. Here’s how to enable safe mode on your Galaxy Note 8:

  1. Turn your phone off.
  2. Then press and hold the Power button past the model name screen.
  3. When the Samsung logo appears, release the Power button.
  4. Immediately after releasing the Power button, press and hold the Volume Down key.
  5. Keep holding the Volume Down key until the phone finishes restarting.
  6. By then you should see the Safe Mode badge at the bottom left corner of the screen. At this point, you can release the Volume Down key.

If the screen doesn’t flicker while in safe mode, then it’s apparently due to some bad apps. Now you can try uninstalling individual apps starting from the most recent app you’ve downloaded before your phone screen started to flicker. Don’t forget to reboot and test your device after removing an app to know when the problem is gone.

Fifth solution: Perform a master reset.

A master reset or factory data reset can be regarded as the last option if none of the given solutions is able to fix the problem and that your Note 8 screen flickering issue persists. It might be due to a more complex error in the phone system like bug-triggered firmware crashes that caused you this problem. And the only way to clear these errors is a full system reset. But it’s also worth noting that this reset will result to data loss as it will wipe everything out from your phone system including your personal information, customized settings, downloaded apps and files. That said, creating a backup would be necessary. If you’re willing to take a chance in this method, then back up your files and follow these steps to proceed with a master reset.

  1. Press the Volume Up, Home (Bixby), and Power buttons simultaneously for a few seconds.
  2. When the Android logo appears, release all buttons and wait for the Android recovery menu options to display.
  3. From the Android recovery menu, press the Volume Down key several times to highlight or select wipe data/factory reset option.
  4. Then press the Power button to confirm selection.
  5. Press the Volume Down key until Yes — delete all user data is highlighted.
  6. Then press the Power button to confirm select. This will instigate the master reset.
  7. When the reset is finished, the Reboot system now option is highlighted.
  8. Press the Power button to restart your phone.

Alternatively, you can reset your Note 8 through settings. Here’s how:

  1. Swipe up on an empty spot from the Home screen to open the Apps tray.
  2. Tap Settings.
  3. Go to Cloud and accounts.
  4. Tap Backup and restore. Doing so will allow you to create a backup of your important data before wiping them all.
  5. After creating backups, go back to the Settings menu.
  6. Tap General Management.
  7. Scroll to and tap Reset.
  8. Then select Factory data reset from the given options.
  9. Tap Reset to continue.
  10. If prompted, enter your credentials.
  11. Tap Continue.
  12. Then tap Delete all to confirm reset.

Wait until your phone completes the reset and restarts. By then you can proceed with the initial setup process.

Service option

A damaged screen component on your Galaxy Note 8 might be the underlying cause of the problem. In this case, none of the aforementioned solutions can fix the issue because what your phone needs is service. Having said that, you will need to take your device to a nearby service center and have it diagnosed by an authorized technician instead. Any found damaged component will then be taken care of properly to get your phone back up and running smoothly.

What to do with your new Samsung Galaxy Note8 with a screen flickering issue [Troubleshooting Guide]

Hardware problems are always very difficult to fix in a phone with all components glued together to resist water from entering and messing up everything. Such is also the case with the new Samsung Galaxy Note8 with IP68 rating (water and dust resistance). However, there are times when hardware issues occur and one of the most common ones is the screen flickering.

But just because the display of your new phone is flickering doesn’t meant it’s a hardware problem. We’ve also encountered this kind of problem with other phones before but they caused by apps or firmware issues. So, we really just can’t be certain what the problem with Note8 is when it has this symptom. We need to troubleshoot to know more about the problem and that’s what we are trying to accomplish in this post.

If you’re one of the owners of the new Note8 and are experiencing a similar concern, continue reading this post as it may be able to help you fix it.

If, however, you’re looking for a solution to a different problem, then take time to visit our Galaxy Note8 troubleshooting page for we have already provided solutions to some common issues with this device. Try to find problems that are similar with yours and use the solutions and workarounds we suggested. If you can’t find something similar and you badly need help, consider contacting us by filling up our Android issues questionnaire. Make sure to provide us with the information we need so that we can help you better. Don’t worry, it’s free.

What to do about the Galaxy Note8 with a flickering screen

A brand new phone should work without a hitch but there are always times when you can get something that has issues out of the box. We can’t control these things and if you’re one of the owners that face this kind of problem, the least you could is troubleshoot your device to know if this is something that can be fixed without any help from a tech. With that being said, here’s what you need to do about it…

Step 1: Reboot your phone in safe mode and observe

We immediately need to rule out the possibility that the screen flickering is caused by a third-party app. We’ve seen cases wherein some apps may cause the display to flicker from time to time especially CPU and graphics-intensive games.

When the problem is at the app level, it can easily be fixed since third-party apps can easily be removed together with all their files and data. That’s why it’s imperative you do this procedure first. Here’s how you run your Note8 in Safe mode…

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.

After you’ve successfully brought your device to run in this environment, continue using it to know if the flickering continues because if it disappeared, then it’s a clear sign the problem is caused by one or some of the third-party apps you installed. In which case, try to check if there are apps that need to be updated and take time to update them. Here’s how it’s done…

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Play Store.
  3. Tap the Menu key and then tap My Apps. To keep your apps automatically updated, tap the Menu > Settings then tap Auto-update apps to select the check box.
  4. Choose one of the following options:
    • Tap Update [xx] to update all applications with updates available.
    • Tap an individual application and then tap Update to update a single application.

If you are already suspecting an app or two, try clearing their caches and data first and if that won’t work, uninstall them and then reboot your phone in normal mode to know if the problem still occurs.

How clear apps cache and data on Galaxy Note8

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > Apps.
  3. Tap the desired application in the default list or tap 3 dots icon > Show system apps to display pre-installed apps.
  4. Tap Storage.
  5. Tap Clear cache.
  6. Tap Clear data and then tap OK.

How to uninstall applications from your Galaxy Note8

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > Apps.
  3. Tap the desired application in the default list or tap 3 dots icon > Show system apps to display pre-installed apps.
  4. Tap the desired application.
  5. Tap Uninstall.
  6. Tap Uninstall again to confirm.

On the other hand, if the flickering continues while in safe mode or if the problem remained even after doing all the procedures above, then there’s a chance it’s a firmware issue. Move on to the next step.

Step 2: Delete all system caches as some may have already been corrupted or obsolete

We’ve also encountered this kind of problem before that started shortly after an update. It suggest that they system caches have something to do with it. We cannot actually pinpoint which cache is causing the problem as there are thousands of them in your phone and average users don’t have access to them. So, to rule this possibility out, you just have to delete all those caches at once and the system will rebuild them during the boot up process.

Just boot your phone up in Recovery mode and then wipe the cache partition and then leave everything else to the system…

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe cache partition’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘yes’ is highlighted and press the Power button.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

After this, closely observe your phone to know if the screen flickering remained and if so, then the last step may help you get rid of it.

Step 3: Bring your phone back to its original configuration

We will still be ruling out the possibility that this problem is due to a firmware issue so we need to try to bring the phone back to its factory default settings. However, all your files and data that are saved in your phone’s internal storage will be deleted so make sure you make a backup. After which, take note of your Google ID and password or better yet, disable the Factory Reset Protection in your phone so that you won’t be locked out after the reset.

How to disable Galaxy Note8 Factory Reset Protection

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > Cloud and accounts.
  3. Tap Accounts.
  4. Tap Google.
  5. Tap on your Google ID email address if multiple accounts are setup. If you have multiple accounts setup, you will need to repeat these steps for each account.
  6. Tap 3 dot icon.
  7. Tap Remove account.
  8. Tap REMOVE ACCOUNT.

How to perform the Master Reset on your Galaxy Note8

  1. Back up data on the internal memory. If you have signed into a Google account on the device, you have activated Anti-theft and will need your Google credentials to finish the Master reset.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight “wipe data / factory reset.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, “Reboot system now” is highlighted.
  10. Press the Power key to restart the device.

Alternatively, you can also reset your Note8 from its Settings menu…

  1. Back up data on the internal memory. If you have signed into a Google account on the device, you have activated Anti-theft and will need your Google credentials to finish the Master reset.
  2. From the Home screen, swipe up on an empty spot to open the Apps tray.
  3. Tap Settings > Cloud and accounts.
  4. Tap Backup and restore.
  5. If desired, tap Back up my data to move the slider to ON or OFF.
  6. If desired, tap Restore to move the slider to ON or OFF.
  7. Tap the back button to the Settings menu and tap General Management > Reset > Factory data reset.
  8. Tap Reset.
  9. If you have screen lock turned on, enter your credentials.
  10. Tap Continue.
  11. Tap Delete all.

If the flickering continues after the reset, then bring your phone back to the store to have it checked or even replaced.

What to do with HTC U11 with a flickering screen issue? [Troubleshooting Guide]

HTC U11 is deemed among the best Android smartphones to date. It is packed with many advanced features, promising every end-user with the best smartphone experience. Nevertheless, the new HTC U11 is also not exempted from issues. Among the commonly raised concern is on a display issue about flickering screen. What could have possibly caused these problems to occur on such a powerful Android handset and what should be done in order  to get them fixed? These are the main questions that will be addressed in this post. Hence, if you have landed into this page while scouring for possible solutions to a similar issue on the same device, then this content might be able to help you. Keep reading to learn more.

But before we go to our troubleshooting, if you happen to be looking for a solution to a different problem, then I suggest you visit our HTC U11 troubleshooting page for we may have already addressed concerns that are similar with yours. Feel free to use our solutions and workarounds. If they don’t work and you need further assistance, you can always contact us by completing our Android issues questionnaire and hitting submit.

What causes the HTC U11 screen to flicker?

There are only two possibilities in this case, either it is  a software glitch or hardware damage. First, your HTC U11 might have something in it that is causing the screen to flicker. Take for instance when certain app becomes corrupted and goes rogue. When the faulty app is opened or running, it may cause the device screen to flicker. The flickering screen in this scenario is one of the symptoms of app malfunction. Another possible software-related issue that can trigger the same display problem on the phone is a broken file like corrupted videos, audios, and other contents. When you try to open any of these corrupted files on your device, most likely they won’t open. Instead, they will cause the app or device itself to act weird as well. There are also other cases where the phone screen flickers after installing an update. Usually in this case, you will need to re-configure or make some adjustments to the display settings and other relevant options. Major updates usually override your current settings so it likely can cause conflicts. There are also some instances wherein the problem is isolated to an application as the screen only flickers when using certain app.

In worst case scenario, screen flickering can be an indication of broken display or hardware damage on the phone. This is most likely the culprit if the problem started after you dropped your phone or soak it wet. Should this be the case on your end, your only hope to fix the problem is a tech repair.

Recommended workarounds and solutions to screen flickering problem on HTC U11

For as long as the problem is not on the hardware, you still can do something in an attempt to fix it by yourself. You may refer to the highlighted solutions and workarounds below should you wish to troubleshoot the flickering screen problem on your HTC handset. Before you proceed, be sure to check your device for any possible signs of hardware damage.

Doing so will save your time and effort in performing unnecessary troubleshooting given that what your device really needs is tech service. Otherwise, you may go ahead and try some applicable solutions.

First method: Reboot your device (soft reset).

Minor software glitches are often rectified by a soft reset or simple reboot on the device. To give this a try and see how it works, follow these steps:

  1. Press the Power button to turn it off.
  2. If the display is off, press the Power button to turn it back on.
  3. Press and hold the Power button and then tap Restart.
  4. Your phone will then boot up.

If your device does not respond when you touch the screen or press the buttons, you can use the hardware keys to have it restart. Here’s how:

  1. Press and hold the Power and Volume Down buttons simultaneously for about 10 to 15 seconds until the phone vibrates.
  2. When the phone vibrates, release both the buttons.

A soft reset won’t affect any data stored on your phone thus considered a safe method to try when dealing with minor flaws on the device software.

Second method: Boot into safe mode and diagnose apps.

To rule out the possibility of a third party app causing the screen to flicker, you can try to boot your HTC U11 into safe mode and diagnose apps in the state. All third-party apps and services are temporarily disabled in this mode, allowing you to easily determine whether or not a third-party app is the main culprit. Here’s how to boot your HTC U11 into safe mode:

  1. While your device is on, press and hold the Power button for a few seconds to turn it off.
  2. Press and hold Power Off when prompted.
  3. When the Reboot to Safe Mode dialog box appears, tap OK.

Your phone will now restart and you should see Safe Mode label at the lower part of the screen. This means that it is already running in safe mode.

Observe your device while in safe mode. If the problem is gone, try to uninstall the recently downloaded app that you suspect is causing the screen to flicker.

  • To uninstall app on HTC U11, open Settings-> Phone-> Apps-> Downloaded-> then select the suspected app and tap Uninstall then OK to confirm action.

To switch back to Normal mode, just restart your device.

Another way to boot into Safe Mode is using the hardware buttons on your HTC U11. Here’s how:

  1. Press the Power button to turn the phone on.
  2. When the HTC logo appears on the screen, press and hold the Volume Down button until you see Safe Mode at the bottom part of the display.

If your phone works as intended and the screen does not flicker while in safe mode, then the problem is triggered by a third-party app rather than a faulty hardware. Remove or uninstall the most recent app you have downloaded on your device then see what happens.

Third method: Wipe cache partition.

To eliminate the possibility about the problem being triggered by some corrupted or broken system files on the HTC U11, performing a wipe cache partition can help. Unlike a factory reset, no personal data will be erased in the process but can yield the same positive results. If you’re all set to give it a shot, then here’s how it’s done:

  1. Power off your HTC U11. Make sure it’s completely powered off.
  2. Press and hold Power and Volume Down at the same time.
  3. When you hear the phone vibrates, release Power.
  4. At the HTC Download Menu, release Volume Down.
  5. To navigate in the menu, press Volume Down repeatedly to highlight the Reboot to bootloader option.
  6. Press Power to confirm selection.
  7. At the No Command screen, press and hold the Power and Volume Up.
  8. Once you’re in Android Recovery release Power.
  9. Press the Volume keys to navigate and highlight Wipe cache partition from the recovery menu.
  10. Press Power to confirm selection.
  11. Wait until the cache partition is completed then highlight Reboot system now option.
  12. Press Power to confirm action.

Observe your device and see if the screen still flickers afterwards.

Fourth method: Master reset (factory reset).

A factory reset, also called a hard reset or master reset should only be considered the last resort should all else failed to solve the problem. The process will revert the phone back to its initial state and factory default settings will be used. This means you will lose all your personal data on your phone storage including downloaded apps, accounts, contents, along with system and app data and settings. With that said, be sure to back up your phone before you for this reset. Here’s how it’s done:

  1. Tap the Apps icon from the Home screen.
  2. Tap Settings.
  3. Tap Backup & reset.
  4. Tap Factory data reset.

Note: Be sure not to select or select the Erase SD card option so as not to delete media and other data from your SD card.

  1. Tap Reset phone.
  2. Tap OK to confirm action.

Alternatively, you can do a master reset or hard reset from startup. Here’s how:

  1. Turn off your phone by pressing and holding the Power button for a few seconds, then selecting the option to Power Off.
  2. Press and hold the Volume Down button and press release the Power button to turn your device back on.
  3. When you see the HTC logo, release both buttons.
  4. Press the Volume Down to highlight Factory Reset option the press the Power button to confirm selection.

Your device will then reboot when the hard reset is finished.

Other helpful suggestions for you to consider:

  • Try to adjust the screen brightness. Sometimes, other devices tend to act a little weird when the screen brightness is set to a higher level or the opposite. To make sure this is not causing the problem, try to adjust the display settings on your HTC U11. Here’s how:
  1. Tap the Apps icon (square dots) from the Home screen.
  2. Tap Settings.
  3. Tap Display & gestures or Display, gestures & buttons.
  4. Tap Brightness Level.
  5. With the Automatic brightness option selected, drag the slider to set the maximum brightness level. Doing so will set a limit on how bright the screen will be when Automatic brightness is selected.
  6. If you want to set the screen brightness manually, clear the Automatic brightness option then drag the brightness slider to the left to reduce the brightness level or right to increase the screen brightness.
  • Try to remove the SD card. If you are using a storage card and the screen flickers with the SD card inside, try to remove the SD card and see if the screen still flickers without the SD card. If the problem persists, then the SD card is good, otherwise, it is the trigger. Reformatting the SD card might be able to fix the glitch or have it replaced with a new one if necessary.
  • Remove screen protectors. If you are using screen protectors, cases or other accessories, try to remove them and see what happens without them on. Some accessories may touch the screen and trigger it to flicker.
  • Close all running apps. If the screen flickering happens when using multiple apps, try to close all apps. If it occurs when running a specific app, try to uninstall that app. If the problem is fixed, do not re-install it.

How to troubleshoot Galaxy A6 2018 with screen flickering issues

Before spending time and effort in performing a bunch of troubleshooting procedures, care to examine your phone screen for any visible signs of damage. This is a must-do if you previously dropped your device or got it wet by accident. Should there be any indications of physical or liquid damage, then repair/service would be necessary.

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:

  1. Launch the Recent Apps menu on your phone. A list of recently used apps will then show up.
  2. Navigate to an app then swipe up to close.
  3. 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:

  1. Press and hold the Power button until the phone vibrates and the Samsung logo appears then release the Power button.
  2. With the Samsung Galaxy logo still on screen, press the Volume Down button.
  3. Keep holding the Volume Down button until Safe Mode appears in the lower-left corner of the Home screen or lock screen.
  4. 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):

  1. Make sure your phone is connected to Wi-Fi Internet.
  2. Go to Play Store and then click Menu.
  3. Tap on My Apps & Games.
  4. Tap to update apps individually.
  5. 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:

  1. With your device powered off, press and hold the Power, Home and Volume Up buttons simultaneously for a few seconds.
  2. Release the buttons when the Android screen appears and the phone loads in Recovery mode.
  3. Press the Volume Down button to highlight Wipe data/Factory reset option.
  4. Then press the Power button to confirm selection.
  5. 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.

Service/Repair Option

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.

But your chance of obtaining quick and ultimate solution is higher if you could pinpoint the root cause. And this is what you should do first. To help you isolate the problem, try to think of what has happened before the onset of the problem. For example, did your Galaxy A5 screen start to flicker after making some changes to the display settings or options other than the brightness level? Or did it begin to occur after installing a new app, contents, or Android update? Prior actions are usually the trigger so that is what you need to find out first. Among the possible triggers for you to consider would include but not limited to rogue apps, corrupted files like photos and videos, broken segments or files in the SD card, and software bugs. Once you’ve successfully dealt with the culprit, you’ll finally find the remedy.

Practical workarounds for screen flickering problem on your Galaxy A5

If you couldn’t get to determine the underlying cause and that you are certain that the flickering issue on your Galaxy A5 is not associated with any type of hardware damage, then you can just go ahead and try every applicable solution and workaround individually and then see which among them is able to fix your device.

Below are generic solutions and suggested workarounds you may consider among your options. Should you wish to troubleshoot the problem right now, don’t forget to backup your data beforehand. It is possible that the problem might have been triggered by complex bugs that would often require more advanced procedures including system resets. And that could mean wiping out all your critical data stored on your phone’s internal storage. Proceed whenever you’re all set.

Adjust or increase screen brightness (temporary solution)

Many of those who have experienced screen flickering issues on their Samsung Galaxy devices have determined that the problem is triggered when reducing the screen brightness below the average level. Turning off auto-brightness features has also done wonders to some so you might as well consider giving it a try on your end then see what happens. For starters, here’s how to adjust screen brightness from your Galaxy A5 notification panel:

  • Swipe your fingers from the top to the bottom of the screen to open the Quick Settings Panel.
  • Touch and drag the brightness adjustment slider to the right to increase the screen brightness.
  • If Auto is selected from the given options, your device will automatically adjust the display brightness based on your environment. Auto is selected by default and can be modified by removing the check from the Auto box. Doing so will let you adjust the screen brightness manually according to your preferences and remain in that level even when the device is restarted.
  • Alternatively, you can use the Galaxy A5 settings menu to adjust the screen brightness to a higher level.  To do so, tap Apps from the Home screen, then navigate to Settings-> Display-> then drag the Brightness slider to the right to brighten the screen.

Remove SD card

As mentioned earlier, some cases of screen flickering and other display issues in Galaxy devices have been linked to a faulty SD card. It turned out that the display functions are likewise get affected when some contents or SD card segments get corrupted. To rule this out from the possible causes, try to remove the SD card (if you have one inserted in your phone) then see if that will fix the problem. Before you remove the SD card, be sure to power off your device completely. You may need to use an ejector tool to pop the SD card out from the tray, if needed. When the SD card has been removed, turn your phone back on then use it without an SD card inserted. Try to reduce the screen brightness to a lower level than the average and then see if the screen would still flicker. Some people have found remedy from removing the SD card and hopefully, you too can get the same positive result from doing so.

Install Android firmware update

If the problem is triggered by some tough bugs that might have infiltrated and wrecked the phone’s display functions, then a software update might be able to rid them off the system and resolve the underlying cause. Thus, if you haven’t already, check and see if a software update is available for your device.

  • To do so, head over to your phone Apps-> Settings-> General-> About device menu. Usually you’ll see a notification if an update is available. If there is, backup your phone then follow the onscreen instructions to proceed with the software update download and installation.

If none of these will work, then continue with the following solutions and workarounds.

Potential solutions to screen flickering and other display issues related to software malfunctions

First method: Reboot or Force reboot

A restart (soft reset) and force restart work by turning your device off and then back on without affecting any data stored on the internal storage. It works the same when removing and reinserting the battery in other Android devices (with removable batteries). Minor issues transpiring randomly in mobile devices like your Galaxy A5 are likely resolved by a simple reboot. In the case where the device becomes unresponsive due to an app malfunction or software glitch, a force reboot would be an alternative solution.  Both of these restart methods are safe as they won’t affect your data. So if this is the first time you notice your Galaxy A5 display to flicker, then most likely it is just a random issue that is triggered by some minor glitches on the phone system. If you haven’t already, try to restart or force restart your device then see if that will fix the flickering display.

  • To restart your Galaxy A5, simply press and hold the Power button until it power cycles. If it’s not responding, do a force reboot by pressing and holding the Volume Down button and the Power button for about 20 seconds.

This will perform a simulated battery disconnect on your device and gives it a clean fresh start. Wait until your phone boots up completely then observe your phone’s screen behaviour.

Second method: Boot into Safe Mode

Booting into safe mode can help you diagnose and determine whether the screen flickering problem is triggered by some bad apps you have recently installed on your Galaxy A5. All third-party apps and services are bypassed or temporarily disabled in Safe Mode thus it will be easier for you to isolate whether or not the problem is caused by a third-party app or stock app. If your Galaxy A5 screen does not flicker while running in safe mode, then it implies that a third-party app is the trigger. In this case, you will need to remove the suspected app from your device as resolution. But if the problem persists while running your phone in Safe Mode, then most likely it’s a hardware issue or some serious system malfunction that requires more advanced solutions. Here’s how to enter Safe Mode on your Galaxy A5:

  1. Make sure that your phone is completely powered off then proceed with the next steps.
  2. Press and hold the Volume Down key.

  7. Tap Settings.
  8. Scroll down to and then tap on Application Manager.
  9. Navigate to the Downloaded section then tap on a recently downloaded app you suspect may be causing an issue. Once you see the app details on the screen, tap on Uninstall.

If you suspect that any of the apps installed on your SD card is the culprit, scroll across to SD card section then repeat the same process.

After uninstalling suspected apps, restart your phone and check if the problem has been resolved. If the problem persists, repeat the same process by uninstalling the next apps you suspect are causing the problem until the problem is resolved. Otherwise, try the next applicable solutions.

Third method: Clear app cache and data

If the screen flickering occurs only when using a specific app on your phone, then that means the problem is isolated to that application. It could be due to some corrupted files that are stored as an app’s cache. As remedy, you can clear the app’s cache and data. Doing so wipes out cache files including corrupted ones that caused conflict.

  1. Tap Apps from the Home screen.
  2. Tap Settings.
  3. Tap Applications.
  4. Swipe through the available apps then tap the application you want to clear the cache.
  5. Tap Storage.
  6. Tap on Clear Cache to clear the cache.
  7. To clear data from the app, tap Clear Data then tap Delete to confirm action.

Please note though that clearing the application data will reset the app to default settings. All user preferences and personal settings including saved bookmarks and passwords will be deleted.

Fourth method: Enter Recovery Mode and wipe cache partition

Recovery mode is a native feature among Android devices. Booting into recovery mode does not require unlocking of the bootloader to carry out necessary system functions like implementing software update and wiping data or cache partition. Wiping cache will erase all temporary files that are stored as cache in the system partition while wiping data option erase all data and resets your device to factory settings. Wiping the cache partition might be necessary if the screen flickering problem is triggered by some cached files that get corrupted and caused conflict to the system functions, particularly with the display. Should you wish to take your chances in this method, then here’s how to enter recovery mode and wipe cache partition on your Galaxy A5:

  1. Power off your device completely.
  2. Press and hold the Power, Home and Volume Up buttons simultaneously for a few seconds.
  3. When the Samsung logo appears, release the Power button.
  4. When the Android logo appears, release the Home and Volume Up buttons at once.
  5. When the Android Recovery menu is displayed, press the Volume Down button to navigate to the menu options then highlight or select Wipe Cache Partition.
  6. Press the Power button to confirm selection.
  7. Wait until your phone is done wiping the cache partition. When it’s finished, it will prompt you with the Reboot system now option.
  8. Press the Power button to confirm selection and reboot your device.

If this won’t help, then consider your last resort which is a factory reset.

Last resort: Factory reset/Master reset

A factory reset or master reset wipes all data from your device. Should the problem be triggered by some tough bugs dwelling in the main system structure, then that should likewise be eradicated in the process. Major system issues are usually resolved by a complete reset on the device so you might as well consider this among your last possible option. Just make sure everything is backed up before you start. You can perform a factory reset through the Settings menu of your Galaxy A5 or by entering recovery mode. Here’s how:

How to fix screen flickering issue on Samsung Galaxy S9 Plus (easy steps)

The screen flickering issue on your Samsung Galaxy S9 Plus could be just a result of a minor glitch in the system or hardware. Such was the case with some of the issues we encountered with the S9’s predecessors. There were also cases wherein the flickering was due to an issue with the screen. Physical damage is often the cause of any screen-related issues especially if the phone got dropped on a hard surface.

Unless there’s an obvious sign of physical damage when this problem started, we have to assume that it’s just a minor issue with the software either it’s with the an app or the firmware. For a brand new phone, a flickering screen is unusual, so all we have to do is to rule out the possibility that it’s a minor issue with the firmware and after that if the problem continues, then you always have the option to bring it back to the store and have it checked by a technician or have it replaced.

Before going further, if you found this post because you were trying to find a solution to your problem, then try to visit our Galaxy S9 Plus troubleshooting page as we’ve already addressed most of the commonly reported issues with the phone. We’ve already provided solutions to some of the problems reported by our readers so try to find issues that are similar with yours and use the solutions we suggested. If they don’t work for you and if you need further assistance, fill up our Android issues questionnaire and hit submit.

What to do if your Galaxy S9 Plus has a flickering screen


The following are things you can do about your phone with a screen problem specifically a flickering display. Try to see if one of the solutions will work for you…

First solution: Reboot your phone

I personally encountered a screen flickering issue with one of my phones a few months ago and all I did was reboot it. I knew for a fact my phone didn’t have physical and/or liquid damage and it was the first time the problem actually manifested so I thought it was just a glitch somewhere. It was indeed a glitch because after I rebooted my device, the issue didn’t occur again even until now. That’s what I want you to do first especially if your phone hasn’t been dropped on a hard surface or got submerged in water for a long time.

If the normal reboot couldn’t fix it, try doing the forced restart procedure: press and hold the volume down and power keys together for 10 seconds or more until the device restarts. This is more effective than the normal reboot as it simulates battery disconnect which refreshes your phone’s memory, reloads all core services and functions and close apps running in the background. However, if the problem can’t still be fixed by this, then try doing the next procedure.

Second solution: Run your phone in Safe mode and continue using it

There are also apps that may cause the screen to flicker especially CPU and GPU intensive games. So the next thing you should do is run your phone up in safe mode to temporarily disable all third-party apps because if one of them is causing the problem, it shouldn’t occur while in safe mode.

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen appearing on the screen.
  3. When SAMSUNG appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. When Safe mode appears in the bottom left corner of the screen, release the Volume down key.

While the phone is in this environment, continue using it so you can closely observe if the problem is still happening. Assuming it’s fixed, it’s obvious that there’s a third-party app that’s causing it. Find out which app it is and then uninstall it:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > Apps.
  3. Tap the desired application in the default list.
  4. To display preinstalled apps, tap Menu > Show system apps.
  5. Tap UNINSTALL > OK.

You may have to uninstall more than on app to fix this problem so be patient and keen observation is key to resolving this problem.

On the other hand, if the problem is still happening while in safe mode, it means that the problem could be in the firmware. The next two procedures you would have to do is for the system itself.

Third solution: Wipe cache partition

This is to rule out the possibility that the flickering is due to some corrupt system caches. By doing this, you’re deleting all system caches but once the phone reboots after they’re deleted, those caches will be replaced with new ones.

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Android logo displays, release all three keys.
  4. An ‘Installing system update’ message will show for 30 – 60 seconds before the Android system recovery menu options appear.
  5. Press the Volume down key several times to highlight wipe cache partition.
  6. Press Power key to select.
  7. Press the Volume down key to highlight yes, them and press the Power key to select.
  8. When the wipe cache partition is complete, Reboot system now is highlighted.
  9. Press the Power key to restart the device.

Your phone will take a little time booting up after the cache partition is wiped off of its contents as it will rebuild or recreate those caches. Don’t be alarmed if the phone gets stuck on the logo for a minute or two after this just don’t turn it off so that what were deleted will be replaced successfully. If the screen flickering continues, then it’s time to reset the phone.

Fourth solution: Backup your files and reset your phone

This the last thing you need to do but if the problem still continues after this, then you really have to bring it back to the store to have it checked and/or replaced. Now, before you actually reset your phone, make sure to backup your files and data as they will be deleted and you may no longer retrieve them if that happens. After the backup, remove your google account from your phone so that the Factory Reset Protection will be disabled and you couldn’t be locked out after the reset.

Here’s how you reset your Galaxy S9 Plus…

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

Press and hold the Volume Down key and then press and hold Power key. Keep them pressed for ten seconds and your phone will reboot normally. Observe your phone to know if the screen still flickers and if so, then we might be dealing with a more serious issue with the firmware or the hardware. Move on to the next step in this case.

Step 2: Boot your P9 in Safe mode and observe

We have to isolate the problem at this point in our troubleshooting because it’s possible one or some of the third-party apps is causing the problem. So, to rule it out, reboot your phone in safe mode to temporarily disable apps you downloaded and installed on your own.

  1. Turn off your Huawei P9.
  2. Press and hold the Power key.
  3. Once the Huawei P9 screen appears, release the Power key and immediately press and hold the Volume Down button.
  4. If successful, you can see ‘Safe mode’ in the lower-left corner of the screen.

While the device is in this mode, observe closely to know if the screen still flickers and if the problem is fixed, then our suspicion that one or some of the third-party apps causes the problem is confirmed. Try to find the apps that might be causing the problem and then uninstall them one by one until the problem is fixed.

However, if the screen still flickers even in safe mode, then the third-party apps have nothing to do with the problem.

Step 3: Try to wipe the cache partition to see if it makes a difference

There are times when system caches used by the firmware become corrupt or obsolete. It could be one of the reasons why performance issues or even problems that have something to do with the hardware happen. Deleting those caches will force the phone to create new ones to replace them and in this case, it’s necessary. You can only delete system caches at once by booting your phone in recovery mode.

  1. Turn off your Huawei P9.
  2. Press and hold the Volume Up and the Power keys together.
  3. When the Huawei logo appears, keep holding both keys until the screen turns black.
  4. The screen may turn black for a second or two and you may release the keys at this point.
  5. When you can see EMUI on the screen, it means you’ve reached your phone’s recovery system.
  6. Using the Volume Down button, highlight “Wipe cache partition” and press the Power key to select it.
  7. Confirm your action and wait for the phone to finish wiping off contents of the cache partition.
  8. It may take for the phone to boot up a little longer but wait for it.

After wiping the cache partition, observe your phone closely to know if the screen is still flickering and if so, then the problem could be with the firmware or the hardware. You need to rule out the possibility that the problem is with the firmware by doing the next step.

Step 4: Reset your Huawei P9 to rule out the possibility of a firmware issue

If all else failed to fix the screen flickering issue on your Huawei P9, then it’s time you reset your device to finally rule out the possibility that this problem is due to an unknown firmware issue. If the problem still occurs after the reset, we can say the problem is with the hardware and you may need help from a technician to do further tests and even fix the phone is possible. But before that, make sure you backup all your files and data and then follow these steps:

  1. Turn off your Huawei P9.
  2. Press and hold the Volume Up and the Power keys together.
  3. When the Huawei logo appears, keep holding both keys until the screen turns black.
  4. The screen may turn black for a second or two and you may release the keys at this point.
  5. When you can see EMUI on the screen, it means you’ve reached your phone’s recovery system.
  6. Now, using the Volume Down button, highlight the option “Wipe data/factory reset” and then hit the power key to select it.
  7. You will be brought to another screen that prompts “Confirm wipe off all user data?”
  8. Highlight the option “Wipe data/factory reset” once again and then hit the Power key to select.
  9. It may take a several seconds to complete the reset so wait for it until it’s done. You can actually see the progress on the screen.
  10. Once the reset is completed, you will be brought back to EMUI screen.
  11. Hit the Volume Up button to highlight “Reboot system now” option and then press the Power key to reboot your phone.
  12. It may take for the phone to boot up a little longer but wait for it.

After the reset and the screen still flickers, you may need help from a technician to get it fixed.

How to fix your LG G6 with screen flickering issue [Troubleshooting Guide]

When the screen of your phone, in this case the LG G6, starts to flicker, we might be tempted to immediately think it’s due to a hardware problem. It’s logical to think about that especially if the device recently suffered a drop since physical damage will greatly take its toll on the screen as it’s the most vulnerable component. However, if the problem started and you know for a fact it’s not due to physical damage, then I suggest you take time troubleshooting your device to know what the problem really is and what needs to be done to fix it.

In this post, I will walk you through in troubleshooting your G6 whose screen started to flicker for no reason at all. We’ve seen this issue before and we’ve seen cases wherein apps caused the problem. There were also cases wherein the screen flickering issue was tied to a firmware problem that resulted from firmware updates or anything that has effects on the performance. So, if you own a phone like this and are bugged by the screen that flickers from time to time, then continue reading to learn how to troubleshoot the problem.

Before going any further though, if you have other concerns with your phone, make sure you visit our LG G6 troubleshooting page where we list down every problem we address each week. Find issues that are similar or related to yours and use the solutions we suggested. If they don’t work for you or if you need further assistance, then feel free to reach out to us by completing our Android issues questionnaire.

Troubleshooting LG G6 with its screen flickering

The purpose of this troubleshooting guide is for us to know why the screen of your LG G6 started to flicker, what caused it to act like that and what needs to be done to fix it. However, there are cases wherein we cannot do anything. For instance, if the flickering is due to a hardware problem, you need to have the phone checked by a technician near you for further testing. But anyhow, here’s what you need to do to troubleshoot this problem.

Step 1: Verify the problem isn’t caused by a glitch

A glitch in the system or the hardware may result to a flickering screen and while it may appear as though it’s a serious problem, more often, it’s not. Glitches can easily be fixed by a reboot but the best thing to do to get rid of the glitch is to forced reboot the phone. Just press and hold both the Volume Down and the Power keys together for 10 seconds and the phone should reboot normally. Observe if the flickering still happens.

A forced reboot is actually the same as the battery pull procedure that we often do to phones with removable batteries. It refreshes the phone’s memory by draining stored electricity in some of the components. Since you’re LG G6 doesn’t have a removable battery, you just have to do the combo to force reboot it but it still has the same result as with the battery pull.

If, however, the flickering didn’t stop by doing the forced reboot, then you must move on to the next step as, clearly, the problem is more than just a glitch.

Step 2: Find if your third-party apps have something to do with it

We’ve seen cases wherein the flickering is due to some apps that take up so much of the RAM and CPU. The screen may flicker when the phone is running low on memory or heated up so much. While we can simply reboot the phone to cool it down a bit or close apps running in the background, it’s better that you reboot your phone in Safe mode to temporarily disable all third-party apps. This way, you’ll be able to tell if the problem is caused by a third-party app because if so, then you just have to find the culprit and uninstall it. Here’s how you boot your LG G6 in safe mode:

  1. With the screen on, press and hold the Power key.
  2. In the options menu that displays, press and hold Power off.
  3. When ‘Restart in Safe mode’ displays, tap OK to restart in Safe mode.
  4. Upon restart, device displays ‘Safe mode’ at bottom of screen.

Of course, there are apps you can’t just uninstall as you may lose data you’ve accumulated, in which case, try disabling it and observe further to know if it really is the one causing the problem. You need to be extra sure about these things to avoid losing your data or progress.

Step 3: Delete the system caches for some of them may have already been corrupted or obsolete

There are times when issues involving a hardware component occur due to corrupt caches and flickering screen is one of them. Since we don’t know for sure what the problem really is, at this point, we just need to rule this possibility out and move on if the issue remains after deleting the system cache.

  8. Wait for the cached data to clear; depending on size, it will take several seconds to complete.
  9. When the wipe is complete, the storage screen refreshes and Cached data shows as 0 B. This means your cached data has been successfully cleared.

  8. When the wipe is complete, the storage screen refreshes and Cached data shows as 0 B. This means your cached data has been successfully cleared.

Step 4: Bring your phone back to factory default settings and see if that makes a difference

After doing the first three steps above and the issue still occurs, then you have no other choice but to backup your data and reset your phone. You have to make sure you create a copy of files you don’t want to lose before the reset because they will be deleted and can no longer be recovered.

Before you begin troubleshooting software issues that might have caused your Nokia 8 screen to flicker, verify and ensure that your apps and device software are updated. You may head quickly to the App Store and check for any apps updates available for your phone. Do the same with your device software.

First solution: Restart/soft reset your Nokia 8.

Various types of software-related issues in mobile devices can be resolved by a soft reset or device restart. If your phone screen flickers only when using certain app or opening a certain file, there is a higher chance that it’s a software issue, which can potentially be remedied by this method. So here’s what you should try performing then:

  1. Press the Power button for a few seconds until the menu options appear.
  2. Select the option to Power off then tap OK. Your phone will then shut down.
  3. After 30 seconds, press the Power button again until your phone turns on.

Alternatively, you can do a soft reset using the hardware keys. This is an alternative method to restart your phone if it freezes when the error occurs. Here’s how it’s done:

  • Simultaneously press and hold the Volume Up button and Power button for a few seconds or until your device power cycles.

Second solution: Enable safe mode.

Third-party apps that have gone rogue may likewise cause your device to act weird and one of the symptoms to transpire when this occurs is an unusual display. To determine whether or not a third-party app is to blame, try booting your Nokia 8 into safe mode and see if the screen still flickers. All third-party apps are bypassed or temporarily disabled in safe mode so if the screen flickering doesn’t occur, it denotes that a bad app is to blame. Here’s how to enable safe mode on your Nokia 8:

  1. With your phone turned on, press and hold down the Power button for a few seconds until the menu options appear.
  2. Tap the option to Power off then select Restart in safe mode.
  3. Tap OK and wait for your phone to restart in Safe mode.

When you see the Safe Mode badge on the bottom left corner of the display, that means you’re already in safe mode. If the screen still flickers while in safe mode, you need to troubleshoot software issues on your device, if not a damaged component.

Third solution: Adjust display settings.

There are cases of screen flickering that are somehow tied to the current display settings on the phone. Others have it that there display would flicker when the brightness is set to high while some when it’s the opposite. To see if this is likewise what’s causing your phone screen to flicker, try adjusting the display settings particularly the brightness level from low to high or vice versa. Here’s how to access and configure display options on your Nokia 8:

  1. Swipe up to unlock your phone screen.
  2. Open the Notification Panel.
  3. Drag the panel downwards or tap the Arrow down icon on the right side of the notification panel.
  4. Drag the screen brightness slider left to right to adjust brightness level. You can try making the screen brighter of darker and see which works.
  5. Alternatively, you can go to Settings-> Display-> Brightness Level.
  6. Move the slider left or right to reduce or increase screen brightness level on your phone.

You can also try enabling Adaptive brightness to see if optimizing brightness level for available light would fix the problem.

Fourth solution: Wipe cache partition.

Cache files are not only dwelling in apps but also in one of your phone’s system directory called the cache partition. While these files may be beneficial to multitasking or reloading of the same data or information, adverse symptoms including screen flickering when any of these system cache files crashed or get corrupted. Should this be the root cause of the problem, wiping the cache partition on your Nokia 8 can potentially fix it. Here’s how it’s done:

  1. Press and hold the Volume Up button for a few seconds.
  2. When the Android logo appears, release the button.
  3. Press the Volume Up button and Power button simultaneously to enter recovery mode.
  4. While in recovery mode, press the Volume Up or Volume Down button to navigate to the given options then press the Power button to confirm selection.
  5. To do a master reset, press the Volume Down button to highlight Wipe cache partition from the given options.
  6. Then press the Power button to confirm selection.
  7. Wait for your phone to finish wiping the cache partition and then instigate device restart.

Unlike a factory reset/master reset, wiping cache partition doesn’t delete your data so it doesn’t result to data loss.

Fifth solution: Restore factory defaults/master reset.

If it’s not hardware damage, the screen flickering problem you’re dealing with could be due to a more complex system error if it persists after performing all prior methods. Your last option and possible solution to try on is a full system reset or restore your device to its factory defaults. Aside from wiping all data, a factory reset will also delete any software bugs and major software errors that might have caused you this trouble. Just be sure to back up all your important data before you do so. The faster way to perform a factory reset, is through the settings menu.

  • To get this done, navigate to Settings-> Backup & Reset-> Factory Data Reset-> Reset Device. Finally, tap Erase Everything to confirm master reset.

Alternatively, you can restore your phone to its factory default settings through Android recovery mode. Here’s how:

  1. Press and hold the Volume Up button for a few seconds.
  2. When the Android logo appears, release the button.
  3. Press the Volume Up button and Power button simultaneously to enter recovery mode.
  4. While in recovery mode, press the Volume Up or Volume Down button to navigate to the given options then press the Power button to confirm selection.
  5. To do a master reset, press the Volume Down button to highlight Wipe data/factory reset option.
  6. Then press the Power button to confirm selection.
  7. Press the Volume Down button again to highlight Yes — delete all user data option.
  8. Then press the Power button to confirm selection.
  9. Wait until your phone is done erasing all your data, customized settings and apps from your device.
  10. When it’s done, the Reboot system now option is highlighted.
  11. Press the Power button to reboot your phone.

Repair options

Service would be necessary if none of the previous solutions is able to fix the screen flickering problem on your Nokia 8. Most probably, your device had acquired some sort of hardware damage either from accidental drops or liquid exposure before. Symptoms of liquid damage may occur later so it’s a possible symptom of liquid damage. In this case, you will need to take your phone to a service center and have it assessed by an authorized technician.

Otherwise, contact your carrier for other options if you strongly believe that the hardware is okay and that the problem is associated with software issues including software bugs and/or erratic apps on the phone.

Solution: If your Samsung Galaxy S7 Edge had not been dropped or has liquid damage then most likely your device has a firmware related issue. In fact, lots of reports we received from our readers saying that after the firmware update the device screen started to flicker without apparent reason. However, since we don’t really know what caused the issue the best thing that you should do is to isolate the problem by performing the basic troubleshooting procedures. Here are the steps that you need to follow:

Step 1: Restart your phone to Safe mode to determine if there were apps triggered it

By booting your phone in Safe mode your device will run all the pre-installed apps in the system and will disable all downloaded applications. So, while in this mode try to observe your device if the issue persists. If not, then most likely a third-party app  caused the problem you can uninstall it and see if the problem will occur again.

However, after the procedure and the screen still flickers then it could be a firmware or hardware-related issue. In that case, you can perform the next procedure for further troubleshooting.

Step 2: Delete the System cache of the phone for it might be corrupted

If the firmware had been updated the device won’t automatically delete all the system caches stored on your phone. Instead, the firmware will continue using it and that may be one of the factors that the problem occurs out of the blue. In this case, all you need to do is to delete all old caches to force the device to create newer caches that is compatible to the new system. Here’s how:

  1. Turn off your Samsung Galaxy S7 Edge.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

So, while in this mode and the issue remained, then you can jump to the next procedure.

Step 4: Perform Master reset to your Galaxy S7 Edge

Before giving a conclusion to the issue the last thing that you can do is to perform a reset on your device. Most of the time, by simply bringing back the device to its factory default may fixed different types of issues like what you have right now. But take note that all your files on your phone will be deleted once you will perform this procedure. So, make sure to backup everything.

  1. Backup your data.
  2. Remove your Google account.
  3. Disengage screen lock.
  4. Turn off your Samsung Galaxy S7 Edge.
  5. Press and then hold the Home and Volume UP keys, then press and hold the Power key.

NOTE: It doesn’t matter how long you press and hold the Home and Volume Up keys, it won’t affect the phone but by the time you press and hold the Power key, that’s when the phone starts to respond.

  1. When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  2. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

NOTE: The “Installing system update” message may show on the screen for several seconds before displaying the Android system recovery menu. This is just the first phase of the entire process.

  1. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  2. Once highlighted, you may press the Power key to select it.
  3. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  4. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.

But if all procedures may not worked on your phone then you can bring your Galaxy S7 Edge to the nearest shop in your area to be checked by the technician.

Galaxy S7 Edge screen went black and white like in Ultra Power Saving Mode

Problem: My girlfriend screen on her s7 edge went black and white and when i go in her setting it’s like her phone is in ultra power-saving mode but it’s not cant get into any of the system settings at all.

Solution: This issue is similar to the problem that I discussed above, there are two things that you need to look into that may have triggered the issue, either the device has a firmware or hardware-related issue. So, before jumping to the conclusion you need to isolate first the issue by performing from one step to the other. At this point, we recommend you to boot your phone to Safe mode to know if there are apps triggered the problem. This procedure will temporarily deactivate all downloaded applications in the system and if the issue is not happening while in this mode, then obviously one of the downloaded apps triggered it. You can uninstall the suspected app until the issue is fix.

However,if the problem remained while in Safe mode then most likely there’s something to do with the firmware or hardware of your Galaxy S7 Edge. In this case, deleting the system cache is the best thing to do to force your phone to create newer files in the system. To do so, you can follow the procedure above.

At this point, after booting in Safe mode and deleting the system caches and issue remained, then you can perform the more complicated procedure by resetting the device. But before doing so try to backup all your files because it will be deleted once the procedure is performed. On the other hand, after the master reset and still the screen is flickering then you don’t have a choice but to bring it to the nearest shop because it might be a hardware issue.

Troubleshooting Huawei P10 / P10 Plus that has flickering screen

If the screen flickering issue on your device started without apparent reason, then you need to troubleshoot it to find out what caused the problem. The most common cause of the screen flickering issue is when the phone got dropped on a hard pavement. Physical damage often takes its toll on the screen shortly after it happened. But whatever the case may be, if your phone suffers from screen flickering issue, this is what you have to do:

Step 1: Forced reboot your phone to rule out possibility of a glitch

System and hardware glitches happen all the time and while they leave an impression that they’re serious issues, they actually are not. More often, glitches can be fixed by a simple reboot which refreshes the phone’s memory, however, to make the reboot even more effective, we suggest you do the forced reboot, which will drain stored electricity in some of the components.

The device will reboot normally after doing this so continue your observation to know if the screen flickering issue still occurs or not and if it does, then it’s time you moved on to the next step for further troubleshooting.

To force reboot your phone, press and hold the Volume Down button and the Power key together for ten seconds or until the phone boots up.

Step 2: Observe your phone’s screen while it’s in safe mode

It’s possible one or some of the apps your downloaded and installed is causing the problem. So, if it’s still happening after you’ve done the forced reboot, then it’s better that you reboot your device in safe mode to temporarily disable all third-party apps. If one of them is causing the problem, then the screen won’t flicker anymore when in this mode. This is how your boot your phone in safe mode:

  1. Turn off your Huawei P10 / P10 Plus.
  2. Press and hold the Power key.
  3. Once the Huawei screen appears, release the Power key and immediately press and hold the Volume Down button.
  4. If successful, you can see ‘Safe mode’ in the lower-left corner of the screen.

Assuming the problem is fixed in this state, it’s clear that the problem is caused by a third-party app. Find that app and then uninstall it to get rid of this problem. However, you may need to uninstall more than one app to fix the issue for good and it’s easier said than done especially if you have a lot of apps in your device. Try to go after recently installed apps or you may have to just backup your files and data and then do the factory reset:

  1. Open Settings.
  2. Touch Advanced settings, then tap Backup & reset.
  3. Touch Factory data reset and choose whether to format your internal storage. Selecting Erase internal storage will delete all files on your internal storage, such as
  4. music and images. Proceed with caution.
  5. Touch Reset phone to restore your device to its factory settings.

Step 3: Delete system caches to rule out possibility corrupt caches cause problem

If the problem started after a firmware update, it’s possible that some of the caches got corrupted and while we really can’t be sure about it, it’s just right to rule it out by following the steps below. You’re not actually just deleting the system caches, you’re forcing the device to replace them with new ones. This is how you delete the system caches on your phone:

  1. Turn off your Huawei P10 / P10 Plus.
  2. Press and hold the Volume Up and the Power keys together.
  3. When the Huawei logo appears, keep holding both keys until the screen turns black.
  4. The screen may turn black for a second or two and you may release the keys at this point.
  5. When you can see EMUI on the screen, it means you’ve reached your phone’s recovery system.
  6. Using the Volume Down button, highlight “Wipe cache partition” and press the Power key to select it.
  7. Confirm your action and wait for the phone to finish wiping off contents of the cache partition.
  8. It may take for the phone to boot up a little longer but wait for it.

If the problem still persists after wiping the cache partition, then you are left with no other choice but to reset your device.

Step 4: Try to bring your phone back to factory default settings

After doing the previous steps and the problem still remains, then you have to do the reset to rule out the possibility that the problem has something to do with the firmware. After the reset and if the issue wasn’t fixed, you need help from a technician who can do further troubleshooting. However, make sure you create a backup of your important files and data as they will be deleted and could no longer be recovered. After which, follow these steps to reset your phone:

  1. Turn off your Huawei P10 / P10 Plus.
  2. Press and hold the Volume Up and the Power keys together.
  3. When the Huawei logo appears, keep holding both keys until the screen turns black.
  4. The screen may turn black for a second or two and you may release the keys at this point.
  5. When you can see EMUI on the screen, it means you’ve reached your phone’s recovery system.
  6. Now, using the Volume Down button, highlight the option “Wipe data/factory reset” and then hit the power key to select it.
  7. You will be brought to another screen that prompts “Confirm wipe off all user data?”
  8. Highlight the option “Wipe data/factory reset” once again and then hit the Power key to select.
  9. It may take a several seconds to complete the reset so wait for it until it’s done. You can actually see the progress on the screen.
  10. Once the reset is completed, you will be brought back to EMUI screen.
  11. Hit the Volume Up button to highlight “Reboot system now” option and then press the Power key to reboot your phone.
  12. It may take for the phone to boot up a little longer but wait for it.

Fix Samsung Galaxy Note 5 that reverts to Swipe Screen Lock even if Fingerprint Lock is enabled, plus other screen related issues

I will tackle some of the screen issues reported by our readers who own Samsung Galaxy Note 5 (#Samsung #GalaxyNote5) and one of them is the issue with screen lock. According to one of our readers, his phone reverts back to Swipe security even if the phone was set to use Fingerprint.

Samsung-Galaxy-Note-5-Smart-Lock

The problem may seem a little complicated but it’s actually very simple and it’s not really a problem but an extra security feature. Read on to know more of this issue and how to tackle it in case you’d encounter it in the future.

There are other problems I included in this post so if you’re currently bugged by an issue or two, continue reading below as it may one of the issues I cited here. Here’s the list of the problems…

If you have other issues, visit our troubleshooting page for the Note 5. Find problems related to yours and use the existing solutions. If they don’t work, then contact us by filling up this questionnaire. All we ask is information so it will be easier for us to help you.

 

Galaxy Note 5 reverts to Swipe when it’s set to use Fingerprint

Problem: I have set unlock screen security to finger print however swipe screen to unlock appears. If I Power off then the finger print appears on unlock screen but reverts back to swipe screen on next unlock screen. Spoke with Samsung and they led me through soft restart and safe mode, still the same. They want me to do a hard reset but not excited about losing everything and if that does not work phone needs to go to a repair center. Is anyone else having this problem. Finger print works okay with all other applications.

Solution: There is a new security feature in all models of Galaxy devices; it’s Smart Lock. You will be able to see this option once you’ve setup your screen lock. Once enabled, you can add your Trusted Places, Trusted Devices and Trusted face so your phone will automatically reverts back to the Swipe screen lock so it will be easier for you to unlock your devices. The same thing happens if the phone detects a Trusted Device is in range and the best example of this is your Bluetooth headset.

In your case, it seems like Smart Lock has been enabled. So, you have two options here; either you clear all your trusted places, devices and/or faces or disable the Smart Lock. Just go to Settings > Security. Under the Screen Security section, you can find Smart Lock. It’s there that you can disable or just clear whatever your phone trusts.

I hope this helps as we’ve received a lot of emails requesting for help.

Galaxy Note 5 replaces numbers on keypad with dashes

Problem: For some unknown reason the numbers on my lock screen will go away and all I have are dashes. I can still unlock the screen by selecting the correct dashes. If I restart I get numbers back but then it does it again. Can I fix it permanently?

Solution: This is a firmware related issue as many started to complain about this after an update. It can temporarily be fixed by reboot, which means it will come back after some time. Many reported that wiping the cache partition will fix this problem, so it’s worth the shot.

  1. Turn off your Samsung Galaxy Note 5 completely.
  2. Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  3. Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  4. Once the Android logo shows, release both the Volume Up and Home buttons.
  5. The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  6. Use the Volume Down key to highlight the option ‘wipe cache partition’ and press the Power key to select it.
  7. When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  8. The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

Galaxy Note 5 shows grey patches on the screen

Problem: Okay well when I was watching a video that had many dark scenes it often showed very light patches of grey so I thought oh maybe it’s just this particular video but no I went to YouTube as well and the same thing happens with dark videos. I always see patches of light grey when it’s dark. Help?

Suggestion: For this kind of problem, we really need to see what you’re seeing so we can determine whether it’s an issue with the screen or not. But one way to know is when those grey patches appear on the same spot regardless whether the screen is in portrait or landscape mode. If they do, then it’s a hardware issue. I hope the touchscreen isn’t affected and I understand if you’re bothered with it. So, I suggest you bring it to your provider and have the tech check it up for  you and you better have it replaced if the problem remains.

Galaxy Note 5 screen sensitivity affected by new screen protector

Problem: I had a screen protector installed and now can’t write a note on the screen when it is turned off. Are only certain types allowed to use this feature?

Suggestion: I am sure there are also instances when the phone doesn’t respond with your touches. Obviously, the screen protector affected the touchscreen sensitivity of your phone. You might disagree with this but the best thing to do about it is to remove the film and find another that works well.

Galaxy Note 5 screen doesn’t acknowledge the S Pen

Problem: When I touch the screen it doesn’t acknowledge the pen.

Suggestion: There are only two possibilities here; either the problem is with the touchscreen or with the stylus. To isolate the problem immediately, test the touchscreen using your fingers. If it responds normally, then the issue is with the stylus; it’s defective and needs to be replaced.

However, to rule out the possibility that it’s just firmware issue, you need to do the master reset first:

  1. Turn off your Samsung Galaxy Note 5 completely.
  2. Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  3. Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  4. Once the Android logo shows, release both the Volume Up and Home buttons.
  5. The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  6. Use the Volume Down key to highlight the option ‘Yes — delete all user data’ and press the Power key to select it.
  7. When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  8. The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

Galaxy Note 5 Screen flickers and won’t turn on

Problem: For no reason at all, the screen just died on me and now it’s flickering or flashing and it won’t completely turn on. It will blink or flicker a little and then turns off after the flicker. I really don’t know what happened and how to fix this problem. I need your assistance. Thanks.

Troubleshooting: Liquid damage? Physical damage? If the phone was dipped in water or was dropped on a hard surface and then this problem occurred, it means you need a technician to check it up, otherwise, try the force reboot as it may be just a system crash: press and hold the Volume Down and Power keys for 20 seconds and the phone will restart.

Galaxy Note 5 screen turned black and white

Problem: Hello. I need your urgent help because my phone’s screen just turned black and white and I don’t like it as it is damn ugly to have a display like this. It is a Note 5 and I bought it brand new. Moments ago, the screen was all colored but suddenly it turned black and white. How can I retain its colors? Thanks.

Troubleshooting: Charge your phone. It seems that it ran low on battery that’s why the grayscale mode was enabled. As part of the Power Saving feature of your phone, the screen will display black and white as it eats up the battery slower than colored display. You have three options as far as this problem is concerned: first, you can charge your phone until the color turns to normal again; second, you can disable grayscale mode; third, you can disable Power saving mode.

The Power Saving mode is under Settings > System, and the grayscale mode is under the Power saving mode.

Emerging among the favoured, high-powered, and hefty smartphones of today is the LG V30. It’s deemed as LG’s best flagship device so far, and likewise one of the best smartphones of 2017. Aside from having a streamlined design, this LG phone is also bursting with features, including a very pleasant OLED display and interesting camera enhancements. Overall, this phone is impressive but likewise imperfect. Evident of this is a widely raised display issue on the LG V30 screen that randomly flickers.

Before we move on, if you are looking for a solution to a different problem, make sure you drop by our LG V30 troubleshooting page for we have already addressed some of the most commonly reported problems with this phone. If you can’t find an issue that are similar with yours, fill up our Android issues questionnaire and hit submit to contact us.

Is it a hardware problem or software issue?


Smartphone problems about flickering displays can either be due to a damaged hardware or software issue. You’ll know if it’s due to a faulty hardware or software based on the problem onset. For example, if the screen starts to flicker and continues to show similar symptoms following an instance of dropping or liquid exposure on your phone, then most likely it’s a hardware-related issue. Unfortunately for hardware problems, a technician’s aid is already required in order to fix your device. On the other hand, you can consider it a software issue if the problem occurs in a sudden without dropping or having the phone wet. Just like when your phone screen starts flickering after installing a new content, app or software update. In this case, it’s probably a software bug that triggers your phone screen to flicker. Fortunately in instances like this, you can try some workarounds and attempt to fix the problem on your end without having to pay extra for service.

To help you get started, I have compiled some helpful solutions that comprised mainly of standard procedures and workarounds to troubleshoot software-related issues including screen flickering on your Android phone. You may refer to this troubleshooting guide whenever you need help.

Potential solutions to screen flickering problem on LG V30

Here’s a rundown of some effective solutions and suggested workarounds that can help you fix the problem with your LG V30 screen that randomly flickers. There’s no definite solution available so you’ll need to try any applicable solutions until you’ll finally get the problem fixed. You may start whenever you’re ready then.

First workaround: Restart your LG V30 (soft reset).

A quick restart fixes most software problems in smartphones, iOS and Android devices. With that said, turn off your phone as you usually do. Keep it off for about 30 seconds, then turn it back on.

  • For starters, just press the Power key then tap Power off and restart-> Restart.

Should the screen flickering issue on your device is caused by a minor glitch on the software, it should be fixed after the restart. If not, then try the next applicable solutions.

A soft reset will not affect any data stored on your phone’s internal memory so you don’t have to worry about data loss in the process.

Second workaround: Adjust screen brightness on your phone.

This simple workaround might likewise be the only thing that needs to be done to rectify the issue. So make sure you don’t skip this.

First try to disable Auto-Brightness then see if the screen flickers or not after doing so.

  • To do so, head over to Settings-> Display-> then tap the option to Disable Auto-brightness on your device.

If the screen still flickers, adjust the screen brightness. Try to reduce the screen brightness and see if that fixes the problem. If not, then try to increase the screen brightness to see if there’s a difference.

Third workaround: Boot into safe mode and diagnose apps.

To narrow down the issue, booting your LG V30 into safe mode can help. While in safe mode, all third-party apps and services are disabled so it will be easier for you to determine whether or not the problem is triggered by a third-party application.

  1. Turn your screen on.
  2. Then press and hold the Power key to display the options menu.
  3. Press and hold Power off option.
  4. If prompted to restart in Safe Mode, tap OK.
  5. Wait until your phone restarts and when it does you should see a Safe Mode label at the bottom of the screen.

Use your phone as you normally do while in safe mode and see if the screen flickering occurs or not. If the problem is gone in safe mode, it denotes that the root cause is a third-party app on your phone. Try to think of which apps you’ve downloaded and installed prior to the onset of the problem then remove or uninstall the suspected apps.

Fourth workaround: Modify or Activate Developer Options on your LG V30.

Many users of Android smartphones who have encountered similar issue on screen flickering were able to find remedy by changing the developer options on their respective devices. The following steps will walk you through the entire process on how it’s done but there may be some slight variations on the menu labels and/or options depending on the device model and variant you have. Should you wish to give it a try, then here’s how to access the Developer Options menu on your LG V30:

  1. Go to Settings-> About Device-> Build Number and then tap it about 7 times or more. Doing so will prompt you with a message saying that you now have developer access.
  2. Press the back button to go back to the Settings menu.
  3. You will then see a Developer options menu above the About Device section. Tap Developer options to view a list of new options.
  4. Scroll down towards the Drawing section.
  5. If you see the Show Surface Updates option enabled, tap the switch to disable it.
  6. Then go down to another section called Hardware accelerated rendering. You will see the option for Disable HW overlays. Tap to enable this option for your device to only use GPU for screen compositing.

Screen flickering usually occurs when your phone switches between CPU and GPU for screen compositing. Enabling this option will delete the option and gets rid of the screen flickers.

Last option: Reset your phone (factory reset/master reset).

Performing a hard reset or factory reset might be needed if the problem is caused by some tough bugs that could not be rectified by any prior solutions. This reset however will wipe out all your phone data including personal information, customizations and more. Any corrupted segment or broken files bugging the Android system will likewise be eliminated in the process. Thus your phone will have a totally clean and fresh start afterwards. The only thing is that you’ll need to spend extra time and effort in redoing the initial setup before using your phone again. Here’s how a factory reset is done on your LG V30 through settings menu:

  1. Back up data on your phone’s internal memory.
  2. Tap Apps from the Home screen.
  3. Tap Settings.
  4. Select the General tab is using the Tab view.
  5. Tap Backup & reset.
  6. Select or clear the check boxes for Back up my data and Automatic restore options.
  7. if necessary, tap Backup account then follow the onscreen instructions to create a Google backup account.
  8. Tap Factory data reset.
  9. Tap Reset phone, then tap Next.
  10. Tap Delete All then OK to confirm.

Wait until the reset is complete, then restart your phone. After the restart, continue with the initial device setup.

Other options to consider if the screen flickering problem persists

  • Repair. If the screen flickering problem persists after doing all prior methods, then there’s nothing more you can do on your end. What you’re dealing with is most likely a hardware issue, which already requires hardware fixing. At this point, your next best option is to take your phone to a nearby LG service center in your place and have it diagnosed by a technician.
  • Replacement. Don’t forget to avail for warranty especially if your LG V30 is still under warranty. If it’s found to be caused by a damaged screen or other display components need to be replaced, then you can use your warranty instead. Doing so will save you from a costly repair.
  • Escalate problem. If you think that the problem is inflicted by a faulty Android update like when it suddenly occurred and persisted after installing a new firmware update version, you may contact LG Support or your device carrier to escalate the problem for them to address it in the next update rollout through an official fix patch. You can also ask for their recommendations while waiting for the fix patch to arrive.
