Samsung's stable Android 12-based One UI 4.0 update is here for the Galaxy S21 5G series
Time to rejoice... and stay cautious
As always (in the last few years, at least), this puts Samsung well ahead of the pack in terms of non-Pixel updates, which is made that much more impressive by the company's long list of proprietary One UI tweaks, add-ons, and performance enhancements.The software overlay is at its fourth big version, aiming to make the Galaxy S21, S21+, and S21 Ultra 5G even smoother, faster, and easier to use than the three early 2021-released powerhouses already are.

If you can download and install the undoubtedly massive update therefore, you should approach it with caution and maybe not gloat too much. Users in some regions are likely to be luckier than others, and you shouldn't be surprised if Samsung needs several days or even weeks to truly spread the love worldwide as far as unlocked Galaxy S21-series devices are concerned.
What's next and what's One UI 4.0 all about?
The wait could be longer for carrier-locked variants (especially in markets like the US), although things progressed at a pretty incredible pace last year. In case you're wondering, the Galaxy S20 family got its first taste of Android 11-based One UI 3.0 in early December 2021... on Verizon of all places, and very soon after, everyone else joined the party both stateside and around the world.
In terms of exactly what you can expect to get under the Christmas tree if you're rocking a new or relatively new Galaxy high-ender, Google's Material You redesign arguably steals the spotlight, with Samsung's take offering deeper than ever customization for basically all visual One UI elements ranging from your phone's home screen to icons, menu, button, background, and of course, widgets.

Samsung's other big One UI 4.0 focus area seems to be the overall security and privacy of your data, which you can keep a closer than ever eye on without making much of an effort. Simply put, Android 12 is all about convenience and customization for the world's largest smartphone vendor, which is clearly a very good thing.
