Solutions to Note10 System UI has stopped error after updating to Android 10

Below are the potential solutions that you can try to fix your Note10 System UI issue.

Refresh the system with a reboot

Whether your Note10 has a problem or not, it’s always a good idea to reboot regularly. Aside from refreshing the system and preventing bugs from developing, a reboot can also be a solution for some cases of minor issues.

A restart has been a staple troubleshooting step across many platforms for many years so you’ll have to do it here as well.

Try restarting your Note10 normally first by pressing the Power button to access the boot menu. Then, select Restart option and see if that works.

Another way to restart the device is by pressing and holding the Volume Down button and the Power key at the same time for 10 seconds or until the device’s screen turns on. This simulates the effect of having disconnected the battery from the device. If this works, this may unlock the device.

If doing the regular restart won’t help, then try this:

  1. Press and hold the Volume Down button first and don’t release it.
  2. While holding it down, press and hold the Power key.
  3. Keep both keys held down for 10 seconds or more.

The second restart procedure tries to simulate the effects of removing the battery pack. On older devices, disconnecting the battery is often an effective way in fixing unresponsive devices. If nothing changed though, proceed to the next suggestions.

Rebooting your device regularly at least once every week can be beneficial. If you tend to forget things, we suggest that you configure your phone to reboot on its own.

You can schedule it to do this task by doing these steps:

  1. Open Settings app.
  2. Tap Device Care.
  3. Tap the 3-dot at the top.
  4. Select Auto restart.

Check the system cache

If your Note10 started showing System UI Error after installing Android 10, the next thing that you must do is to check the system cache. This cache is used by Android to load apps quickly. Sometimes, a major software update may affect this cache. Once it becomes corrupted, it may result to all sorts of problems.

To check if the system cache is bad, try clearing the cache partition. Here’s how:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby / Power key.
  3. When the green Android logo displays, release both keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. The Recovery screen menu will now appear. When you see this, release the buttons.
  5. Use the Volume Down button until you are highlighting ‘Wipe cache partition.’
  6. Press the Power button to select ‘Wipe cache partition.’
  7. Use Volume Down to highlight Yes.
  8. Press the Power button to confirm the action to clear the cache.
  9. Wait for a second as the system wipes the cache.
  10. Press the Power button again to reboot the device. This will return the device to the normal interface.
  11. That’s it!

Troubleshoot System UI app

System UI is one of core system apps that Android uses to do tasks. And just like any other apps, it can encounter bugs or be affected by other bad apps. It can also be troubleshot using the given tools for each app. For this app, there are three troubleshooting steps that you can do to directly deal with it:

  • Force close System UI app
  • Clear System UI cache
  • Delete System UI data

Force close System UI app

This one will ensure that the app is rebooted. This is usually effective for minor, temporary bugs that may develop within the app if left running for a long time.

To force quit an app:

Method 1: Close an app using Recent Apps key
  1. On your screen, tap the Recent Apps soft key (the one with three vertical lines on the left of the Home button).
  2. Once the Recent Apps screen is shown, swipe left or right to look for the app. It should be here if you managed to run it previously.
  3. Then, swipe up on the app to close it. This should force close it. If it’s not there, simply tap the Close All app to also restart all apps.
Method 2: Close an app using App Info menu

Another way to force close an app is by going within the app’s settings itself. It’s a longer way compared to the first method above but it’s equally effective. You want to use this method if you plan on doing other troubleshooting for the said app like clearing its cache or data. Here’s how it’s done:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap the More settings icon (three-dot icon, upper right).
  4. Tap Show system apps.
  5. Find and tap the app.
  6. Tap Force Stop at the bottom.

Clear System UI cache

Should a forced app reboot won’t help, the next good thing that you can do is to delete the cache of the app. This can work if the app’s cache has become corrupted.

To clear an app’s cache:

  1. Go to the Home screen.
  2. Tap Apps icon.
  3. Open Settings app.
  4. Tap Apps.
  5. If you’re looking for a system or default app, tap on More settings at the upper right (three-dot icon).
  6. Select Show system apps.
  7. Find and tap the appropriate app.
  8. Tap Storage.
  9. Tap Clear Cache button at the bottom.

Delete System UI data

If you continue to have Note10 System UI Error, Android 10 update may have damaged the app’s data. What you can do in this case is to reset the app to return its settings to defaults.

To clear an app’s data:
  1. Go to the Home screen.
  2. Tap Apps icon.
  3. Open Settings app.
  4. Tap Apps.
  5. If you’re looking for a system or default app, tap on More settings at the upper right (three-dot icon).
  6. Select Show system apps.
  7. Find and tap the appropriate app.
  8. Tap Storage.
  9. Tap Clear Data button.

Update all apps

Updating Android 9 to Android 10 does not mean that apps are updated automatically. You either have to wait for your device to notify you of pending updates, or you must check manually.

To check for Play Store app updates on your Galaxy Note10:
  1. Open Play Store app.
  2. Tap More settings icon at the upper left (three-horizontal lines).
  3. Tap My apps & games.
  4. Tap Update or Update All.

If you are on Cellular Data connection, we suggest that you update via wifi only to avoid additional charges. This is for you to avoid unnecessary data charges.

To update apps via wifi only:
  1. Open Play Store app.
  2. Tap More settings icon at the upper left (three-horizontal lines).
  3. Tap Settings.
  4. Tap App download preference.
  5. Select Over wifi only (select Over any network if you don’t have wifi).
  6. Tap Done.

Make sure to also keep your apps updated all the time by enabling auto-update option. This is going to save you time if you are the type who is constantly on the go.

To enable auto app update:
  1. Open Play Store app.
  2. Tap More settings icon at the upper left (three-horizontal lines).
  3. Tap Settings.
  4. Tap Auto-update apps.
  5. Tap Over wifi only (select Over any network if you don’t have wifi).
  6. Tap Done.

If you have apps taken from outside the Play Store, you may need to update them by installing an updated APK. Work with the app developer to know exactly what to do.

Check for bad third party apps

One of the main common reasons for many Android problems is bad third party apps. Some apps may suddenly become incompatible when a new Android OS version is installed. This happens if the said app is designed for older Android OS versions only.

To check if there’s a broken app in your device, you want to restart to safe mode. In this mode, all third party apps are blocked (greyed out) so they can’t run. If Instagram runs normally and won’t crash on safe mode, that means that you have a bad app at hand.

To restart to safe mode, follow these steps:

  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.

Don’t forget: safe mode blocks third party apps but it won’t tell you which of them is the real cause. If you think that there’s a rogue third party app in the system, you must identify it. Here’s what you need to do exactly:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your Galaxy Note10 is still problematic, repeat steps 1-4.

Reset app preferences

System UI has stopped error can be due to a missing or disabled default app. Apps need other apps in order to perform tasks. To ensure that all needed apps by System UI are up and running, you can clear the app preferences option.

To reset app preferences:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Reset app preferences.
  5. Restart your Galaxy Note10 and check for the problem.

Clear the software with factory reset

If your Note10 has System UI error after updating, the new Android 10 version may have messed up some aspects of the software. If nothing has worked so far, you must consider wiping the device by performing a factory reset.

Factory reset will delete everything, so you want to make sure that you create a copy of your personal data such as photos, videos, documents, texts, etc. ahead of time. To see if factory reset is effective, follow the steps below.

Method 1: How to hard reset on Samsung Galaxy Note10+ via Settings Menu

This is the easiest way to wipe your Galaxy Note10+. all you have to do is to go under Settings menu and follow the steps below. We recommend this method if you have no trouble going under Settings.

  7. Tap Delete All to confirm action.

Method 2: How to hard reset on Samsung Galaxy Note10+ using hardware buttons

If your case is that the phone is not booting up, or it boots but Settings menu is inaccessible, this method can be helpful. First, you need to boot the device to Recovery Mode. Once you successfully access Recovery, that’s the time that you begin proper master reset procedure. It may take some tries for you before you can access Recovery so be patient and simply try again.

  1. If possible, create a backup of your personal data ahead of time. If your problem prevents you from doing that, then simply skip this step.
  2. Also, you want to make sure that you remove your Google account. If your problem prevents you from doing that, then simply skip this step.
  3. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  4. Press and hold the Volume Up key and the Bixby / Power key.
  5. When the green Android logo displays, release both keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
