The message “Bubble” is a feature introduced in Android 11 that acts as Facebook Messenger’s “Chat Heads”. Conversations can pop up in windows that cover your current activity. If you do not want to use Bubbles, it can be disabled.
Bubbles are an opt-out feature, which means they are enabled by default. When an app presents a bubble for the first time, you have the option to turn off bubbles for the specific app. If you want, it is also possible to turn off Bubbles for all apps completely.
Disable bubbles for specific apps
On your Android phone or tablet, swipe down from the top of the screen (once or twice depending on the device manufacturer) and then tap the gear icon to open the “Settings”; menu.
Scroll down and select “Apps and notifications.”
Select “See all (X) apps” at the top of the screen where “X” is the number of apps you have.
Tap the app you do not want to use Bubbles.
Finally press “Bubbles”.
Change the setting to “Nothing can bubble.”
Now that you get a new message in that app, you no longer see a bubble.
Disable bubbles for specific conversations
When an app supports bubbles, you will see a small icon at the bottom right of the message. Tap it to move the conversation to a floating window.
Tap “Manage” below the pop-up window.
This opens a context menu with options for the app. Tap “Do not bubble conversation” to disable bubbles for this specific conversation.
Disable bubbles completely
If you’d rather disable the message bubbles for all apps, you can too! On your Android phone or tablet, swipe down from the top of the screen (once or twice depending on your device) and then tap the gear icon to open the “Settings” menu.
Select “Apps and notifications.”
Then tap “Messages”.
Tap “Bubbles” in the upper section.
Turn off the “Allow apps to display bubbles.”
Now no apps will be able to use Bubbles. You can return to this screen at any time to re-enable the Bubbles feature.
