Clear App Cache/Data:

NOTE: If one of your apps crashes, freezes, or doesn’t work as intended, you can try fixing these issues by clearing the app’s cache or data.

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

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

Clear the Phone’s Cache Partition:
