How to fix “Unfortunately system UI has stopped” on Galaxy S10

The cause of Unfortunately system UI has stopped error is usually software by nature so the fix is usually done by the user. Learn what you can do if you have this error on your Galaxy S10.

Unfortunately system UI has stopped fix #1: Force stop System UI app

Your Samsung device has many core and default apps that should be enabled and working. These are apps that are needed by Android and other apps in order to do their tasks. One of such apps is the System UI app. Just like any other app, System UI may encounter a bug from time to time, especially when there’s system-wide changes like after an update. Fortunately, fixing minor app bugs is easy. What you have to do is to simply force close the app. Her’es how:

On your screen, tap the Recent Apps soft key (the one with three vertical lines on the left of the Home button).

Once the Recent Apps screen is shown, swipe left or right to look for the Settings app. It should be here if you managed to run it previously. 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.

Another way to force close an app is this:

  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 Settings app.
  6. Tap Force Stop.

Unfortunately system UI has stopped fix #2: Force reboot

Should the problem return after rebooting the app itself, the next thing that you want to do is perform a soft reset. This should clear the system and possibly get rid of the bug as well. To do that, simply press and hold the Power and Volume Down buttons for about 10 seconds. Once the phone has restarted, release the buttons. This is usually effective in clearing bugs that developed when a system is left running for some time. We suggest that you restart your S10 using this method at least once a week to lessen the chances of bugs.

For some Galaxy S10, there may be a slightly different way to arrive at the same method. Here’s how:

  1. Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. You can use the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Wait for up to 90 seconds for the reset to complete.

Deleting the system cache may sometimes help in fixing app troubles. This type cache is necessary for efficient performance of apps. Android uses the system cache to load apps quickly. Sometimes, this cache may become outdated or corrupted which then leads to problems. In most cases, apps may perform poorly or slowly. At other times, some apps may stop working at all. To ensure that the system cache on your device is updated, you must clear the cache partition, where this cache is stored, regularly. 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 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.

  7. Tap Clear cache button.

All you have to do is to tap on them and install the updates. To manually check for updates:

  1. Open Settings app.
  2. Tap Software update.
  3. Tap Download and install.

  1. Open Play Store app.
  2. Tap More settings icon (at the upper left).

Unfortunately system UI has stopped fix #7: Check for rogue apps

If the error happened right after installing a new app, you should delete the app and see if it fixes it. If not, then you continue to troubleshoot for the possibility of a bad third party app issue. To do that, you want to restart the device to safe mode.  Here’s how to do that:

  1. Press and hold the Power button until the Power off window appears then release.
  2. Touch and hold Power off until the Safe mode prompt appears then release.
  3. To confirm, tap Safe mode.
  4. The process may take up to 30 seconds to complete.
  5. Upon reboot, “Safe mode” appears in the lower-left of the home screen.

Remember that third-party applications are disabled in this mode so what you can use are pre-installed apps. If the touchscreen issue won’t appear on safe mode, that means that the problem is due to a bad app. Uninstall the app you recently installed and see if that will fix it. If the problem remains, use the process of elimination to identify the rogue app. Here’s how:

  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 S10 is still problematic, repeat steps 1-4.
