To get Facebook Messenger conversations to appear in floating bubbles on a Samsung Galaxy phone, enable Bubbles in Galaxy notification settings and then turn on Chat heads in Messenger. Where available, a new message can then appear as a movable bubble you can tap to reopen and reply to a conversation. The exact menus depend on your Galaxy model and software version.

Turn on Messenger bubbles in both settings

Samsung’s floating-bubbles guide documents this route for One UI 3 through One UI 6. The phone setting and Messenger setting do different jobs, so complete both.

  1. Open Settings on your Galaxy phone.

  2. Tap Notifications, then Advanced settings.

  3. Tap Floating notifications and select Bubbles.

  4. Open Facebook Messenger.

  5. Tap Menu (three horizontal lines), then tap the Settings icon.

  6. Find Chat heads and switch it on. If Messenger prompts you to open phone Settings, follow the prompt and enable the requested setting.

Samsung notes that some Messenger pop-up controls are app-specific: “Some messenger settings like chat heads and pop-ups can only be controlled in the app, and not through the device’s Settings menu.” Samsung Support’s floating-bubbles guide describes the phone and app steps.

Open, move, or dismiss a bubble

When a message arrives, tap its bubble to open the conversation and reply. Drag the bubble to move it. To dismiss it, press and hold the bubble, drag it to the bottom of the screen, and release it over the X.

Know which kind of pop-up you want

“Pop-up” can mean different Galaxy and Messenger behaviors. Use the option that matches what you want to appear:

Feature What appears Where to configure it Important distinction
Messenger Chat heads / Bubbles A floating conversation bubble that reopens a Messenger chat. Galaxy Settings and Messenger: enable Bubbles on the phone, then Chat heads in Messenger. Both controls are part of Samsung’s documented Messenger procedure.
Smart pop-up view A small icon for a selected app notification that can expand into a pop-up window. Settings > Notifications > Advanced settings > Floating notifications; select Smart pop-up view, then choose apps under Included apps. Samsung says it works only with apps that support Multi window. It is a different behavior from a Messenger conversation bubble.
Brief or Detailed notification pop-up style A notification presented using a Brief or Detailed style. In One UI 8, open Settings > Notifications > App notifications > [app] and find Notification pop-up style. This changes notification presentation; it does not keep a Messenger conversation in a floating bubble. Samsung’s One UI 8 guide was last updated April 19, 2026, and notes that menus can vary.

Samsung documents the Smart pop-up view and One UI 8 styles separately from Messenger’s Chat heads. The Galaxy floating-bubbles guide covers the former; the One UI 8 notification guide covers Brief and Detailed styles.
