Which mobile operating system features "Live Tiles" for app updates on the home screen?

The mobile operating system that features "Live Tiles" for app updates on the home screen is Windows Phone. Live Tiles provide a dynamic way for users to receive real-time information straight from their applications without having to open them. This feature allows tiles to change in size and display updated content such as notifications, news, and other relevant information at a glance, significantly enhancing user engagement and accessibility of information.

In contrast, the other operating systems do not have a feature specifically called "Live Tiles." iOS and Android use a more static approach with icons on the home screen, although both have notification centers and widgets that can provide some level of interactivity and updates. Symbian, which is less commonly used today, also does not support this particular feature. Windows Phone was uniquely positioned with Live Tiles to create a more informative and visually engaging experience on its home screen.
