Clear App Data/Cache:

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

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

  1. Open “Settings
  2. Go to the “General” tab
  3. Scroll to “Phone management” and tap “Apps
  4. Select the desired app and tap “Storage” > “Clear cache
  5. If clearing the cache didn’t help, tap “Clear data” > “OK” (check WARNING above)

Clear the Cache Partition:

NOTE: If your phone 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 these issues by clearing the phone’s cache partition. This can have similar results to a factory reset without losing any personal data on the device.

  1. Open “Settings
  2. Access the “General” tab
  3. Scroll to “Phone Management” and tap “Storage
  4. Access “Internal storage
  5. Wait for the phone to finish calculating the data and tap “Cached data” > “Clear” to confirm

NOTE: If clearing the cache partition didn’t help, you can visit this thread for a guide on how to factory reset the device instead.
