Whether it is possible to display and synchronise Facebook contacts or not depends on which version of the Facebook app you have.
Note! Later versions of the Facebook app cannot synchronise contacts with the Contacts app.
To display Facebook contacts in the Contacts application
- Find and tap Contacts.
- Tap the menu button (three vertical dots), then tap Filter.
- Unmark the Contacts with phone numbers and Online contacts checkboxes
- Under Display contacts, depending on your Facebook setup, select Facebook or Xperia with Facebook or both, then make sure all checkboxes are marked. If you're using a later version of the Facebook app, these options are not available, as the Facebook app doesn't support synchronisation with the Contacts app.
- When you're done, tap OK or Done.
