The latest update also repaired a problem that was affecting owners of certain HTC phones like the HTC One. Some models manufactured by the Taiwan based manufacturer were produced without a physical menu key, like HTC's new flagship model. These handsets had to use an on-screen menu key for Twitter, which reduced the amount of real estate available for the app itself.
The update to Twitter last week left some HTC phones showing the menu bar, which was left as non-functional. That bar has now been removed by Monday's update, returning some real estate back to the app user. Oh, also improved with this update is the UI for Honeycomb flavored Android tablets. Don't remember that build? It was a tablet-optimized version of Android that was available for slates launched after Gingerbread but before Ice Cream Sandwich.
