Clear App Cache/Data:

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

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

  1. Tap “apps” on the home screen
  2. Open “Settings
  3. Scroll to “Device” and tap “Applications
  4. Go to “Application Manager
  5. Swipe to “Downloaded” or “All
  6. Select the desired application
  7. Tap “Clear cache
  8. If clearing the cache didn’t help, tap “Clear data” > “OK” to confirm (check WARNING above)

Wipe the Cache Partition:

NOTE: If your smartphone crashes, freezes, runs out of storage inexplicably or otherwise doesn’t work as intended and you’re considering factory resetting it, alternatively you can try fixing the issues by clearing the phone’s cache partition. This can have similar results to a factory reset without losing any personal data stored on the phone’s internal memory.

  1. If necessary, turn the phone OFF
  2. Press and hold “Power”, “Home” and “Volume Up” at the same time

  6. Press “Power” to confirm
