For a very long time, the Facebook app on Android was atrocious, and it's still not great. The folks at Facebook are trying, though. After starting a Play Store beta program not long ago, the social network is now setting up an alpha channel to test the newest (and potentially most unstable) features. Want in?
The alpha program will be run in a very similar way to the beta program. You'll have to sign up for the Play Store testing program and the app will update as new builds are released.
