I disabled the built-in FB app on my Adroid devices, which is as far as I think I can go in thwarting FB from uploading info on all my contacts, but I have no idea if it actually helps.
I wonder why Google insists on preventing Adroid users from uninstalling the FB app.
Must be a carrier thing, I don’t have FB app on my phone. I do have apps from Tmobile and Samsung I would like to delete but can’t.
