There are plenty of ways to display notifications on phones, but one of the most recognizable has been promoted by Messenger created by Facebook. We are talking about characteristic bubbles that allow the user to see how many unread messages he or she has from a given conversation, and a specific notification will appear on the screen only when new messages appear in the conversation. Clicking on the bubble gives you the opportunity to immediately respond to received messages. This feature appealed to Google owners who have been trying to make similar notifications on Android for several years. This idea appeared without much publicity in the beta version in Android 10.
Although the feature has been added to the system, it is disabled by default. To enable it, you need to access Developer Options and then find "Bubbles" option in them. Due to the fact that this function is not available by default in the system, it proves that it's not completely ready, but everything indicates that Google will add it in stable version to Android 11. So far, beta version of notifications in bubbles works with the official application Messages developed by Google.
