How Do I Fix System UI Has Stopped?

“System UI Has Stopped” is a common error on Android. The message is repeatedly displayed on the phone screen when the device interface fails and may vary by the system depending on the smartphone manufacturer. “Unfortunately, the System UI has stopped”, “The System UI has stopped”, or “The system interface is not responding” are some of the ways that the alert can be displayed on the phone.

First, it is important to know the system user interface to understand the cause of the error. The term comes from the English word “User Interface” or “UI”, which can be understood as any visual element displayed on the screen that is not part of an application. Check out the following list of ways to fix the Android system error “System UI has stopped”.

Reset application preferences

You can set a default program on your phone if there are two or more apps that perform the same function. For example, when you open a photo on Android devices, you often have to choose to use the Gallery or the Google Photos app.

To ensure that you do not always have to choose which application to view the images in, you can set a default program by selecting the “Always” option. This creates app preferences on the phone and undoing that choice (i.e. resetting app preferences) may fix the UI problem.

To do this, go to the settings and look for the “Applications” tab. Then tap the three dots icon in the top right corner of the screen. Then press “Reset application preferences” and confirm with “Reset”. Keep in mind that resetting this setting will erase the defaults for all apps on the phone.

Clear Google App cache

Caching data from Google apps such as Play Store, System UI, Play Services, and others can increase the memory load of the smartphone and cause slow performance or incorrect behavior of the app. Therefore, clearing the application cache can resolve the “System UI has stopped” error.

Open your phone settings and go to “Storage”. Then tap on “Internal Storage”. To continue, tap “Apps” and tap “View System” from the three done icons on the right side of the screen. Then tap on apps and finish by selecting the “Clear cache” option.

It is important to note that this process can vary depending on the phone manufacturer. Another option is to use caching apps for trading such as Google Clean Master and Files.

Follow these steps to clear the cache and data:

  • Step 1: Open Settings and go to Apps or Apps & Notification or System apps.
  • Step 2: Tap the three dots icon at the top and select Show System Apps. If you don’t see the three dots icon, go to All Apps. Then tap the icon with the three dots.
  • Step 3: Now under System Apps, search for System UI. Touch it.
  • Step 4: Tap Storage followed by Clear cache. Restart the phone. If the problem persists, tap Clear Data or Clear Storage, depending on the option available on your device.
  • Step 5: Repeat the steps for Google App, Google Play Store, and Google Play Services.

Updating System and Play Store Apps

System apps, such as Google Play Store and Play Services, update automatically in the background, but in some cases, the update may contain a bug or glitch, causing a bug in the system interface. Therefore, updating system applications manually can solve the problem.

To perform the procedure on Google Play services, go to your phone settings and tap on “Applications”. Then choose the “Google Play Services” option and tap the three dots icon in the top right corner to uninstall Google Play Services updates. You also need to clear the application cache in “Storage”. When you open a Google app, it automatically displays a message for the user to update Google Play services. Tap “Update” to finish.

To update the Play Store, open the application and go to “Settings” in the menu on the left side of the screen. Scroll down the page until you find the Play Store version and tap. If an update is available, the Play Store will be updated automatically. The UI error can also be caused by other apps so it is important to always update programs in the Play Store.

Remove Google App Updates from Play Store

The system UI error could be caused by a Google App update. Therefore, uninstalling the update may solve the problem as the Android platform relies on your service to run other apps. To perform the procedure, go to the device settings and go to “Applications”. Search for your Google app and tap the three dots icon in the top right corner. Finally, uninstall updates and reboot your phone.

Remove Widgets From the Phone Home Page

Widgets are graphical interactions that serve to facilitate access to smartphone tools, such as music player, clock, calendar, or Google Search. Removing widgets from the screen should fix the system error as some may not be compatible with your phone. To do this, just touch and drag them to the “X” at the top of the screen. Don’t forget to reset the phone after doing the procedure.
