No twatter, no fb, no snap chat, no instagram. Before I even enabled anything on my Phone, I followed this Tutorial. Allows removal of ANY bloatware on an Android. Cleaned that biotch up before ever inserting a SIM Card in it!
Remembered Q saying that even if FB was never signed in to on a Phone or Tablet, [they] had capability to pull data even if it was uninstalled. Reason is, there are 3 services and the installed .apk for FB. Using ADB, it allows the uninstall of the .apk, and the three services that always run. Same with the other programs.
