Samsung is breaking with tradition this year when it comes to assigning version numbers to its minor One UI updates. Instead of One UI 3.5, we’re getting One UI 3.1.1 later this year, with the Galaxy Z Fold 3 and Galaxy Z Flip 3 likely to be running it out of the box.

As usual, Samsung will then bring the newer version to existing devices. The Galaxy S21 series was always expected to be first in line for the One UI 3.1.1 update, and a Samsung forum moderator has just confirmed it, along with giving us a time frame for when the update will arrive.

Galaxy S21 One UI 3.1.1 release to coincide with Galaxy Z Fold 3 launch
One UI 3.1.1 for the Galaxy S21 series will start rolling out at the end of August, once next month’s security patch has been released for those phones. That coincides with the release date of Samsung’s new foldables, which is expected to fall somewhere between August 20 and August 27.
