If you want to delete comment off your status, and aren't able to do so with the most recent FB for Android application - just uninstall the update. I did.
Remember, to delete a friend's comment...swipe from right to left over the comment or directly across from the post.
Don't you wish the Developer would just get it right, for once. And yes, I can live with this app, but I love the option to delete inappropriate comment(s).
