Neither Android 13L nor Android 14

Like last year, Google has not launched the “L” iteration of Android 13 this year. Samsung’s One UI 4.1.1 is based on Android 12L for Galaxy Z Fold models and tablets, however, the One UI 5.1.1 appears to be based on the Android 13 operating system for all.

Google started Android 14 Beta, but do remember that Samsung One UI 5.1.1 which was spotted in the development stage is still based on Android 13 OS. With the One UI 6.0 update, the company will bring Android 14 OS to Galaxy devices.
