The introduction of App Pairs in Android 15 allowed users to select two applications for split-screen usage and add a shortcut to the home screen. However, users with smaller devices faced challenges with the 50:50 split-screen ratio. Android 16 improved this by offering flexible split-screen ratios like 70:30 and 90:10, enhancing the multitasking experience. Users can set up a pairing of applications, such as Chrome and Gemini, with one app occupying 90% of the screen. To create an App Pair, users open the desired applications, access the multitasking view, select the split-screen option, and adjust the ratio by dragging the handle. After setting the preferred view, users can save the app pair for easy access, with the system remembering the last used split-screen ratio.
