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

WARNING! When you clear an application’s data, all personal information stored within the app will be deleted. This includes profiles, settings, save files, high scores, login and credit card information etc. To avoid losing personal app data, clear ONLY the app’s cache.

  2. Access “Settings
  3. Scroll to “Device
  4. Tap “Applications” > “Application manager
  5. Swipe to “All” or “Downloaded
  6. Select the desired application
  7. Tap “Clear cache
  8. If clearing the cache didn’t solve the problem, tap “Clear data” > “OK” (check WARNING above)

Wipe the Phone’s Cache Partition:
