Facebook pushed an update to its Android app today that brings a handful of useful photo features, like the ability to post an image as a comment – something that's been available on the web for quite a while. Otherwise, you can now also delete and/or edit photo albums, untag yourself in photos, and upload multiple images at the same time. Group admins can now easier pin and unpin posts, as well.
It seems like Facebook is also edging closer to a full rollout of the new flat UI – more and more users are reporting that it's available for them, though it's still not yet available for everyone. Good things come to those who wait, I suppose. Unless you're waiting for Facebook to remove the Gingerbread-style menu from devices with physical keys – that still hasn't happened.
