Introduced at the Galaxy Unpacked 2021, the Samsung Galaxy S21 series comes with Android 11-based One UI 3.1 out of the box. It is an upgraded version of the 3.0 iteration of the One UI and brings few exciting new features and smart camera functions for enhanced user experience.

Now, as per the latest info, AT&T pushed new software updates for the Galaxy Note 20, Galaxy S20, and Galaxy Z Fold 2 5G in the US. However, the carrier has already delivered the Android 11-based One UI 3.0 version to these devices, the new update brings the latest One UI 3.1 changes.

Samsung One UI 3.1 lets users shoot dynamic photos and videos with new smart camera features including improved Single Take, touch autofocus, autoexposure controller, Object eraser tool, and Multi Mic Recording. Moreover, it also allows you to extend your Galaxy device to your desktop PC using Samsung’s Wireless DeX.


On the other hand, One UI 3.1’s Eye Comfort Shield mode automatically adjusts the blue light based on the time of day. Besides, it also enables users to remove the GPS data that reveals the location of photos before you share them. Lastly, the compatible Galaxy Buds can switch between your Galaxy phone and tablet running on One UI 3.1 seamlessly.

Alongside the One UI 3.1, the new software also brings improvements to the system security of the Galaxy Note 20, S20, and Z Fold 2 models by installing the February 2021 security patch. According to AT&T support pages, these firmware update weighs over 1.5GB so it is suggested that users should download over a Wi-Fi connection.

Samsung One UI 3.1.1: Eligible Devices, Features and Release Date



Last year, Samsung started & concluded the Android 11-based One UI 3.0 update rollout for most of its eligible Galaxy devices. Later on, the company introduced a minor upgraded version called One UI 3.1 alongside the Galaxy S21 series flagships.

Following this, the Korean tech giant announced that it will deliver the new One UI 3.1 features and changes to its several compatible phones and tablets until Q3 2021. However, the company is directly bringing the 3.1 version of the One UI instead of One UI 3.0 with the Android 11 upgrade.

If we take a look at the naming strategy of Samsung’s custom software skin, we found three iterations of every One UI version including – x.0, x.1, and x.5. Though we were expecting that things will remain the same and the company will announce the 3.5 version of One UI along with its next flagship smartphones this August.

Have you received the Android 11 upgrade and your Galaxy phone or tablet is currently running the One UI 3.1? Are you waiting for the One UI 3.5 update? You might never get it as Samsung is going (reportedly) to change its tradition of One UI versions.

History of Samsung One UI

  • One UI 1.0, One UI 1.1 and One UI 1.5
  • One UI 2.0, One UI 2.1 and One UI 2.5
  • One UI 3.0, One UI 3.1 and One UI 3.5 then, what?

One UI 3.1.1 will come next?

It is said that Samsung Galaxy Z Fold 3 and Galaxy Z Flip 3 will come with a truly new One UI 3.1.1 version instead of the expected One UI 3.5. The reason behind this decision is unknown, at the same time, the arrival & rollout plan of the 3.1.1 version of One UI is still in the air.
