Facebook scraped call, text message data for years from Android phones

This past week, a New Zealand man was looking through the data Facebook had collected from him in an archive he had pulled down from the social networking site. While scanning the information Facebook had stored about his contacts, Dylan McKay discovered something distressing: Facebook also had about two years worth of phone call metadata from his Android phone, including names, phone numbers, and the length of each call made or received.

This experience has been shared by a number of other Facebook users who spoke with Ars, as well as independently by us—my own Facebook data archive, I found, contained call-log data for a certain Android device I used in 2015 and 2016, along with SMS and MMS message metadata.

If you granted permission to read contacts during Facebook's installation on Android a few versions ago—specifically before Android 4.1 (Jelly Bean)—that permission also granted Facebook access to call and message logs by default. The permission structure was changed in the Android API in version 16. But Android applications could bypass this change if they were written to earlier versions of the API, so Facebook API could continue to gain access to call and SMS data by specifying an earlier Android SDK version. Google deprecated version 4.0 of the Android API in October 2017—the point at which the latest call metadata in Facebook user's data was found. Apple iOS has never allowed silent access to call data
