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.

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

  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.
