Samsung officially starts rolling out One UI 4 with Android 12 for the Galaxy S21 family

Over the past few weeks Samsung has been testing the update to One UI 4 based on Android 12 in public on members of its Galaxy S21 flagship smartphone family, and today is finally the day you've all been waiting for. The company has announced that it's officially rolling out One UI 4 to the Galaxy S21, S21+, and S21 Ultra. This comes mere hours after an inadvertently posted rollout schedule first revealed that these handsets would get the update this month.

As usual with such things, while the rollout starts today, expect it to take a few weeks to reach every single device out there.

But wait, there's more. There's also a new update headed to the Galaxy Watch, Galaxy Watch Active, Galaxy Watch Active2, and Galaxy Watch3 wearables that will enable "users to enjoy enhanced health features and new watch faces".

Samsung doesn't go into any more detail than that, so it's unclear where exactly the One UI 4 update is going to roll out first. Our money would be on the company's home country of Korea, but we'll have to wait and see. Reports from users should be coming in within hours, we assume.

One UI 4 comes with reimagined widgets, a host of new Color Palettes, a wider variety of emoji features, as well as more GIFs and stickers available from the keyboard. The new software version will alert you when an app is attempting to use your camera or mic, and it includes a new privacy dashboard that sticks all of those settings in a convenient place.
