Troubleshoot issues related to apps on your device

This article helps troubleshoot malfunctioning applications on your Samsung Galaxy S9

You may have an unstable application if it:

  • Doesn't open
  • Crashes frequently
  • Freezes or becomes unresponsive
  • Displays error messages

These steps help identify and resolve the underlying cause. After completing each step, test to see if the issue is fixed. If not, continue to the next step.

  1. Perform a soft reset.

    A soft reset deletes any temporary files that may be causing the issue, but does not erase any of your content or data.

    1. Turn off the device by pressing and holding the Power/Lock key, then tap Power off.
    2. Wait 10 seconds.
    3. Press the Power/Lock key to turn the device back on.
  2. Clear application cache.

    Note: Clear the application cache on your applications to free up space and improve performance. Be sure you clear only the application cache and not the application data. When you clear the application data, it removes your personal settings and info such as login information and high scores. Clearing the application cache does not erase any of your content or data. Below are the steps to clear application cache:

    1. From the home screen, swipe down on the Status bar.
    2. Tap the Settings icon.
    3. Scroll to and tap Apps.
    4. Scroll to and tap the malfunctioning app.
    5. Tap Storage.
    6. Tap CLEAR CACHE.

  3. Clear application data.

    Caution: When you clear application data, you're permanently deleting your user information, settings, high scores, credit card information, and other files that weren't downloaded originally.

    When you clear application data, the application resets to look like the first time you opened it.

    1. From the home screen, swipe down on the Status bar.
    2. Tap the Settings icon.
    3. Scroll to and tap Apps.
    4. Scroll to and tap the malfunctioning app.
    5. Tap Storage.
    6. Tap CLEAR DATA.
    7. Tap DELETE to confirm.

  4. Uninstall and reinstall the application that isn't working.

    A complete application uninstall removes all related files, settings, and data from your Samsung Galaxy S9. After the uninstall, reinstall it to try to fix any download errors and to be sure you have the latest software version of the application.

  5. Uninstall an application.

    Download and reinstall the application.

Note: To optimize device performance, be sure your Samsung Galaxy S9 is running the most recent device software. Check for software updates.
