Clear an App’s Cache/Data:

NOTE: If 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 will be deleted, including user profiles and login information, save files etc. To avoid losing personal app data, clear ONLY the app’s cache.

  1. Open “Settings
  2. Access “Apps
  3. Select the desired app
  4. Access “Storage” > “Clear cache
  5. If clearing the app’s cache didn’t help, try “Clear data” (Check the WARNING above)

Wipe the Phone’s Cache Partition:

NOTE: If your phone freezes, crashes, runs out of storage inexplicably or otherwise doesn’t work as intended and you’re considering factory resetting it, alternatively you can try clearing the phone’s cache partition.

  6. Highlight “Wipe cache partition” and press “Power
  7. Highlight “Yes” and press “Power” again to confirm
  8. Once done, ensure “Reboot system now” is highlighted and press “Power” one last time

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