On Tuesday, Samsung launched its beta program for Android 12 and One UI 4. Along with the list of many new features and updates for the Samsung Galaxy S21, S21+, and S21 Ultra is support for eSIM in the US. eSIM allows a smartphone to be registered to a network without needing a SIM card. You'd only need to provide a unique eSIM number to your carrier to activate service.
Galaxy S21 variants outside of the US come fitted with dualSIM trays while the US variant's supports a single nanoSIM at a time. Android 12 will enable eSIM support for the Galaxy S21 lineup with the option to use dualSIM modes.Samsung Galaxy S21 and its dualSIM card tray (EU)
As of this writing, the beta program has reached its capacity from the US. Other markets where the One UI 4/ Android12 beta is live include South Korea, UK, China, Germany, and Poland.
One UI 4 brings updated configuration options for the home screen, new icons, wallpapers, and updated AR emojis. There are also new notification indicators that will let you know when an app is using the phone's camera or microphones.
The Galaxy S21 series will receive the stable release of Android 12 at the end of its beta phase, sometime in the next few months. Google may officially release Android 12 source code AOSP (Android Open Source Project) on October 4 and the general public release is expected to coincide, though no date has yet been confirmed by Google.
