Clear App Cache / Data:

NOTE: Assuming one of your third party apps doesn’t work as intended or takes up too much storage, you can try fixing these issues by clearing the app’s cache / data.

  3. If necessary, tap the “General” tab
  4. Scroll to “Phone Management” and tap “Apps
  5. Go to the “All” or “Downloaded” screen
  6. Select the desired app and tap “Clear cache
  7. If clearing the cache didn’t help, tap “Clear data” > “Yes

  3. Scroll to “Phone Management” and tap “Storage
