Clear App Cache/Data:

NOTE: If an app crashes, freezes, or takes up too much storage inexplicably, you can try fixing it by clearing the app’s cache and/or data.

  1. Open “Settings
  2. Access “General
  3. Go to “Apps” and select the desired app
  4. Tap “Storage” > “Clear cache
  5. If clearing the app cache didn’t fix the issues, tap “Clear data” > “OK” (check the WARNING above)

  2. Go to “Phone Management” and tap “Storage
  3. Tap “Internal storage
  4. Wait for the phone to finish calculating the data
