Last year, Google was spotted testing bubbles for its own Android Messages app , Google suggested to developers that they test the bubbles API. Users will see new options in Facebook Messenger’s settings menu with three choices to choose from: all conversations can bubble; selected conversations can bubble; and nothing can bubble.
To use the Facebook Messenger bubbles, an Android user must be toting a phone running the Android 11 developer preview or beta. In addition, Messenger version 2184.108.40.206.118 (beta) must be installed. XDA notes that bubbles will appear on the side of a Messenger user’s phone display. Tapping on the bubble will bring up a floating window where a user can quickly type out a response and keep a chat alive even while multitasking.
Most Messenger users familiar with the Chat Heads system employed by the app probably won’t notice any difference once the switch to bubbles is made. And don’t forget that if you’re using an iOS device, Facebook’s Chat Heads/bubbles will only appear on Facebook which severely limits the usefulness of the feature on that platform.
