Facebook is testing out a feature that would enable them to push an update to their Android app without requiring users to visit Google Play. The Facebook app on your phone would download and update the app automatically or it would vibrate until you install it.
The new version of Facebook for Android would also let you change your profile picture using the mobile app and hide stories / report spam. You will also be able to start group messages quickly. The app’s new permissions includes a bullet point that says “download files without notification.”
“We’re working quickly to improve Facebook for Android and want to make sure everyone is using the best version of our app. You’ll experience these updates when you are on Wi-Fi, and they won’t rely on your data plan,” stated a Facebook product manager.
