The display of message previews as floating icons, often referred to as heads-up notifications, can be customized on Android devices. These previews, commonly seen with messaging applications, provide quick access to conversations directly from the screen. Disabling or modifying this functionality enhances user control over visual alerts and screen clutter. A common example is the circle that pops up on the screen from a SMS application.
Managing these on-screen notifications contributes to a more streamlined user experience. It allows for prioritizing information and reducing distractions. Historically, control over such notification features has evolved with each Android operating system update, providing increasingly granular control over the visibility and behavior of app alerts. This feature are very useful to make important chat notifications.
