The author transitioned from a Samsung device to the Pixel 10 Pro and appreciates the new app bubbles feature introduced in Android 17 Beta 3, which allows users to launch apps in a movable and collapsible window. This feature is particularly useful for multitasking, such as accessing notes or media while using other apps. However, the author notes that app bubbles have limitations, including a cumbersome process to open them, lack of resizing options, and issues with returning to full-screen mode. In contrast, Samsung's pop-up windows offer more flexibility and convenience. Despite these drawbacks, the author remains hopeful for improvements to app bubbles in future updates.
