If you need help with doing any step, visit the Devices page, select your device, and find the steps.


"App has stopped" and "Force close" errors

  1. Update the device software to the latest version. Visit the Devices page for current versions and steps.
  2. Open the Play Store, and download all app updates. Make sure you get all updates to fix bugs or compatibility with your device software.
  3. If you know the app causing the error, search for the app giving problems in the Play Store.
    • Look at the user reviews. Pay extra attention to the reviews left by people with the same/similar device.
    • If recent reviews mention issues, the problem is with the app. Send feedback to the developer, and uninstall the app until it's updated and fixed. The developer needs to fix these errors, and T-Mobile can't do more about it.
  4. If you know the app causing the error, clear the app cache and app data for the app. (Visit your Devices page, and use the Manage Apps page for help.)
  5. Wipe the cache partition to clear system memory. (Visit your Devices page, and use the Device Reset page for help.)
  6. Test if the errors return. If they do, continue below.
  7. Soft reset and remove your SD card, if you have one.
    1. Remove the battery, if possible.
    2. Remove the SD card. We're going to test without it, in case it has a problem.
    3. If you removed the battery, re-insert it and turn on the device.
    4. If the battery is not removable, perform a soft reset. (Visit your Devices page, and use the Battery page for help.)
  8. Uninstall and reinstall the app giving errors, if possible.
  9. Uninstall downloaded apps such as:
    • Task manager apps
    • Battery saver apps
    • Launchers or home screen apps
    • All apps you downloaded around the time the problem started
  10. Clear all app caches. This may work on devices with Android 4.2 and up:
    1. Go to Settings, and tap on Storage or Storage & memory. There you can find the amount of memory consumed by apps and media.

    2. Tap Cached data which also displays the amount of cached data on your device.

    3. Tap OK to delete all your app cached data.

  11. Check your device has enough free storage space. T-Mobile recommends having at least 15% of the on-device storage free.
  12. Restart the device.
  13. Test if the errors return. If they do, continue below.
  14. Perform a master reset on the device. (Visit your Devices page, and use the Device Reset page for help.)
  15. If the above steps have not solved this issue, contact the device manufacturer or check out Google's help: Fix an installed Android app that isn't working - Android Help.
