Just use that front-facing camera power wisely
Vine has just been updated in the Play Store to enable what every self-loving kid on the internet needed -- front facing camera support. Nothing else in the interface for recording has changed, except now you have a simple button in the bottom left corner of the app to toggle between cameras. You can toggle in the middle of a video between cuts if you just have to give that reaction shot, or you can go the full 6-seconds with one camera or the other.
Is this enough to bring people back over from Instagram with video? Hard to say that it is. Regardless, you're likely about to see your Vine feed filled up with a lot more faces for the next few days. You can grab a download from the Play Store link above.
