Clear App Cache/Data:

NOTE: If 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 cache or data.

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

  1. Open “Settings
  2. Access “Phone management
  3. Tap “Storage” > “Internal storage
  4. Wait for the phone to finish calculating the data
  5. Tap “Cached data” > “Clear
