Update to Facebook Messenger for Android Allows Users to Draw, Type Over Photos

Android Police was the first to report on the update, describing how the feature works:

While in a chat, tap the photo icon in the bottom control row. You’ll see the now-standard horizontal photo reel. Slide left or right to find the one you want, then select either the “Aa” (text) or pen icon. You can doodle or type to your heart’s content, which should be very handy for elaborating on complex driving directions.
