The Samsung Galaxy Z Fold7 and Samsung Galaxy Z Flip7 will be launched around July and will most likely use One UI 8 based on Android 16. With Android 16 confirmed to be launched this June, it is unreasonable to still use Android 15.
The probability of these two foldable screen devices using One UI 8 is increasing after Samsung launched One UI 8 Beta for the Galaxy S25 series yesterday. In fact, this year Google started development of Android 16 much earlier since November 2024. With the device launched with the latest version of Android, the 7+7 years of update support provided by Samsung is more worthwhile.
Android 16 will bring a new interface design through Google Material 3 Expressive which is more cheerful, expressive and easy to use. It is not only used on smartphones, but also on Wear OS 6.
