Facebook is opening its Messenger app to beta testers on Android and looking for feedback on its user experience. The program aims to cast a wider net on catching bugs before they ship to general public. While testers will likely have a bumpier experience than users with the general release version, there’s potential to test unreleased features that might never make the public edition.
