Clear App Cache/Data:

NOTE: If one of your applications crashes, freezes, takes up too much storage inexplicably or otherwise doesn’t work as intended, you can try fixing this behavior by clearing the app’s cache and/or data.

WARNING! Clearing an app’s data will result in the deletion of all your personal data stored within the app, including credit card and login information, high scores, settings, user profiles etc. To avoid losing personal app data, clear ONLY the app’s cache.

  1. Open “Settings
  2. Scroll to and tap “Applications
  3. Select the desired application and access “Storage
  4. Tap “Clear cache
  5. If clearing the cache didn’t help, tap “Clear data” > “OK” (check WARNING above)
