Hundreds of apps available through the Google Play store and Galaxy Store have been updated to deliver a seamless, foldable experience. Samsung and Google set up test labs in cities across the globe to work with partners and developers to test and verify that their apps and services are optimized for the Galaxy Fold and the Android ecosystem. Google introduced changes in Android 10 to offer improved resizable activity, multi-resume functionality and an updated Android Emulator to help support multiple-display type switching.
