Wipe App Cache / Data:

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

WARNING! Clearing an app’s data will result in the deletion of all your personal information stored within the app, including settings, profiles, high scores, login and credit card information etc. As such, it’s recommended to try clearing only the cache, and clear data only if clearing the cache fails to give results.

  1. Open the apps drawer
  2. Access “Settings
  3. If necessary, tap “Menu” and select “List view
  4. Scroll to “Device” and tap “Apps
  5. Swipe to “All” and select the desired application
  6. Tap “Clear cache
  7. If necessary, tap “Clear data” > “Yes

Clear the Cache Partition:

  2. If necessary, tap “Menu” > “List view
  3. Scroll down to “Device” and tap “Storage
