Clear App Cache/Data:

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

WARNING! When you clear an app’s data, all your personal data stored within the app will be lost, including save files, user profiles, credit card and login information etc. To avoid losing personal app data, clear ONLY the app’s cache.

  1. Open the apps drawer
  2. Go to “Settings
  3. Scroll to “Applications
  4. Tap “Application manager
  5. Go to “Downloaded” or “All
  6. Select the desired app
  7. Tap “Clear cache
  8. If clearing the cache didn’t help, tap “Clear data” > “OK” (check WARNING above)
