Facebook makes it a habit to test new features before release, and one of them is a permanent notification bar that popped up for some Android users last year. Now, that feature's back, and it even comes with an upgrade: it shows your profile picture right next to Facebook's familiar icons. Just like the first time around, the bar stays in Android's notification tray whether or not you have a new message or friend request. The only difference this time is that your face will stare right back at you every time you access the tray. As is usually the case with Facebook's experimental releases, only a small pool of users has access to the tool right now. If you happen to be one of them and hate having to look at yourself all the time, don't worry: simply click the "i" icon to disable the bar via the Settings page.
