Foldable devices bring different screen size and shape to the market. Hence, the way people
use your app may vary from past years. By considering new layouts and navigation patterns,
app developers can explore opportunities to build greater experience in larger screen
devices.
Handle diverse aspect ratios
On devices where your application takes up the entire screen, large-screen form factors mean
you need to allow for various aspect ratios. For example, in the Samsung Z fold series, the
aspect ratio of the cover screen is similar to a bar-type device, whereas the ratio of the
main screen is close to square. Take a communication app, users may place it in a tall,
narrow window at the edge of the screen so they can view and respond to messages while
working with another app that occupies the rest of the screen.
