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.

  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)
