“System UI stopped” is a common error on Android. The message is displayed repeatedly on the phone screen when the device interface fails and may vary on the system according to the smartphone manufacturer. “Unfortunately the system UI has stopped,” “System UI has stopped” or “System Interface is not responding” are some of the ways the alert can be displayed on the phone.
First, it is important to know what the system UI is to understand the cause of the error. The term comes from the English word “User Interface” or “UI” can be understood as any visual element displayed on the screen that is not part of an application. Check out the following list of 6 ways to resolve the Android system error.
Reset App Preferences
You can set a default program on your phone when there are two or more apps that perform the same function. For example, when opening a photo on Android devices, you usually need to choose to perform the action with the Gallery or the Google Photos app.
So you don’t have to choose every time in which app you want to view images, you can set a default program by selecting the “Always” option. This creates apps preferences on the phone, and undoing that choice (i.e. resetting apps preferences) can solve the user interface problem.
To do this, go to settings and look for the “Applications” tab. Then tap the three-point icon located at the top right of the screen. Then press “Reset app preferences” and confirm in “Reset”. Note that resetting this setting will clear the defaults of all applications on the phone.
Clear Google App Cache
Caching data from Google applications such as Play Store, System UI, Play Services, and others can increase the smartphone’s memory load and cause slow performance or incorrect application behavior. Therefore, clearing the app cache may resolve the error “system interface has stopped”.
Access the phone’s settings and then go to “Storage”. Then tap “Internal Storage”. To continue, press “Apps”, and on the three ready icons on the right side of the screen, tap “Show System”. Next, tap applications and finish by selecting the “Clear Cache” option.
It is important to note that this process may vary depending on your phone manufacturer. Another option is to use caching applications to perform the action, such as Google Clean Master and Files.
Update System and Play Store Apps
System applications such as Google Play Store and Play Services are automatically updated in the background, however, in some cases, the update may present a bug or failure, generating the error in the system interface. This way, updating system apps manually can fix the problem.
To perform the procedure in Google Play Services, go to the phone settings and touch “Applications”. Then choose the “Google Play Services” option and touch the three-point icon in the top right corner to uninstall the Google Play Services updates. You also need to clear the app cache under “Storage”. When you open any Google application, a message will be displayed automatically for the user to update Google Play Services. Touch “Update” to complete.
To update the Play Store, just access the app and go to “Settings”, in the menu located on the left side of the screen. Scroll through the page until you find the Play Store version and tap. If an update is available, the Play Store will update automatically. The user interface error can also be caused by other apps, so it is important to always update the programs in the Play Store.
Uninstall Google App Updates from the Play Store
System UI error may be caused by a Google App update. So uninstalling the update may fix the problem, as the Android platform depends on its service to run other applications. To perform the procedure, access the device settings and go to “Applications”. Search for your Google app and tap the three-point icon at the top right. Finally, uninstall the updates and reboot your phone.
Remove Widgets from the Phone’s Homepage
Widgets are graphic interactions that serve to facilitate access to smartphone tools such as music player, clock, calendar, or Google Search. Removing widgets from the screen should resolve the system error, because some of them may be incompatible with the phone. To do this, simply touch them and drag them to the “X” located on top of the screen. Don’t forget to reboot your phone after performing the procedure.
Restart the phone
Restarting the phone is a simple option, but can solve the problem of the user interface error. This is because the action clears the temporary files and thus frees up more memory space for the smartphone to work without errors. Press the power button on the phone and tap the “Reset” option.
