Message bubbles, sometimes referred to as chat heads, are floating icons displaying conversations that appear on top of other applications. On the Android operating system, these bubbles provide quick access to messaging apps. Disabling this feature removes the floating icon, requiring the user to open the messaging application directly to view and respond to messages. For instance, turning off bubbles for the Messages application will prevent the circular chat icon from appearing over other apps when a new text message is received.
Removing message bubbles can improve screen visibility by eliminating potentially distracting overlays. This can enhance the user experience, particularly when multitasking or using applications where screen real estate is limited. Furthermore, some individuals prioritize privacy and may prefer to avoid visual indicators of active conversations on their screen. Early iterations of chat head-like features were popularized by third-party applications before becoming integrated into the Android OS.
