Facebook trick pls look at the details?

[Rahul]

In the Facebook android app. Under the favorites there is an option Find Friends. After that if we select contacts. Another option comes that says “FIND PHONE CONTACTS ON FACEBOOK.” After selecting they show me many Facebook users, saying that these users in Facebook are in my contact list.
What I think is that Facebook makes a screening of all the contacts in my phone and if these contact no are associated with any any Facebook user they show me the name.

My question is out of so many users I can relate ONLY FEW OF them with my saved contacts. But others I can not relate. My question is that how to know the suggest Facebook user are saved with which contact no or contact name in my contact list of phone.. Very urgent pls help

You Have to Look at your Contact List on your phone to See if Facebook Saved them to your Phone
