ALTHOUGH I LIKE the clever avatars that Facebook has embedded into my Android phone book, I don' t like the fact that Facebook has hoovered more than 700 phone numbers directly from my phone. So I deleted them from Facebook.
This might have happened to you too, if you’re a Facebook user with one of Facebook’s mobile applications installed on your smartphone. I discovered that nearly every contact that I had on my phone was also stored on Facebook’s servers. This means Facebook has the private phone number of several Secret Service agents now because they were on my phone. None of those guys has a Facebook account but Facebook now has their names and phone numbers. This happened because I probably approved the use of a term or a condition when I set up Facebook sync. I should know better. I followed the following steps to remove my phone's contacts from Facebook.
1. Visited facebook.com from my latop and logged in via the top-right corner of the screen where I clicked on Account and then Edit Friends.
2. In the menu on the left side of the screen, clicked on Contacts. I saw hundreds of my contacts that came from my phone, listed along with their phone numbers.
3. On the right side of the screen, I clicked on the “this page” link and followed the instructions. I clicked the Remove button.
4. I disabled contact-sync in Facebook’s mobile app.
