Facebook for Android has been updated to version 1.9, bringing performance improvements (read: faster feed scrolling), a some new picture sharing and messaging features. You may not be able to get it quite yet on the device Play Store, but forcing the download from the web Play Store should do the trick, as usual. Here's the changelog:
-Improved performance and various bug fixes
-More messaging features like creating group messages and adding friends to existing group conversations
-Shortcuts to share photos and messages right from your home screen
I've already noticed smoother operation in the main feed when scrolling, and the new photo share button on the main feed page is pretty handy, too.
