Why are facebook uploading all my mobile contacts !
I recently downloaded my Facebook data to see what they had. Even for me an experienced web head, I was surprised at the information they had, including contacts names and phone numbers of people not related to my contacts on Facebook.
So I realised Facebook had been secretly uploading contacts from my phone.
I investigated further and checked the “Continuous Contacts Upload” setting was turned off on both my Android and iPhone.
Facebook for Android:
1. Tap Menu icon.
2. Tap App Settings.
3. Tap Continuous Contacts Upload to turn this setting on or off.
iPhone or iPad:
1. Tap Menu icon.
2. Tap Settings > Account Settings > General.
3. Tap Upload contacts to turn this setting on or off.
Then I typed into facebook.com help “why are facebook uploading my contacts”.
At the bottom of the results I noticed it said “Turning off contact uploading in the Facebook app doesn't automatically turn off contact uploading or call and SMS (text messaging) uploading in the Messenger app.“
So I looked in the Messenger app and think that was the offending app that uploaded my contacts even though “contact uploading” was disabled…
In Facebook Messenger app > Click on your Profile image > People > Manage Contacts >
I also created two test contacts on my mobile to see if Facebook is still uploading my mobile contacts, so when I do a data download in the future I can search for those hidden numbers. If the new hidden numbers in my Facebook data download, the problem will not be fixed.

p.s. When the EU sue Facebook for privacy invasion again. I wish some of that money would go to the ordinary citizens affected.
