Motorola took the feature out as of Android 4.1
Why are my Facebook contacts not appearing on my device?
Facebook contacts will no longer sync with the Android Contacts app [on Android OS 4.1 and later].
The Android Contact list is built to provide data portability, and Facebook provides contact data that cannot be exported from the device.
Facebook contacts can still be accessed on the phone through the Facebook app.
While we cannot guarantee or warranty a third-party application, some owners have reported success syncing Facebook contacts using Ubersync and Haxsync.
