Samsung has rolled out its Android 13 update to many phones and tablets, branded as One UI 5.0, but the Korean OEM introduced a minor revision with the Galaxy S23 series. The One UI 5.1 update was hinted to arrive on select phones and tablets, but the company didn't specify any official roadmap. Nonetheless, the rollout has already started in full swing, as the Galaxy S22, S21, S20, as well as the foldables have picked up the new release.
Galaxy S22
The stable One UI 5.1 update for the Galaxy S22 has gone live in Europe and parts of the US, according to user reports. The update weighs nearly 2GB, and besides a host of new features, it also brings along the latest February 2023 security patches.
For the Exynos-powered variant, the new firmware comes in the form of software version S90xBXXU3CWAI. In case of the US carrier models, the build number should be S90xUSQU2CWAI.

It’s worth noting that Samsung decided to ship a new bootloader with the One UI 5.1 update for most of the devices. As a result, there's no way to downgrade to an older build after installing the release on your phone.
Download One UI 5.1
As always, the updates for the aforementioned devices are rolling out in batches, so you might have to wait a couple of days before the update notification pops up on your device.
In case you haven’t received the OTA prompt on your phone yet, you can head over to the Software Update section in the Settings app to check if the update is available for your device or not. You can also grab the stable One UI 5.1 release directly from the company’s Firmware Update Server (FUS) and flash it manually on your Galaxy device.
