New updates are being added at the bottom of this story…….

Original story (published on February 09, 2021) follows:

Samsung has been doing a tremendous job with the Android 11 rollout. The company has even released the stable update to its mid-range devices such as the Galaxy M30s, Galaxy A51 5G, and Galaxy A71 5G.

This is actually a step in the right direction for the South Korean giant since it has left one of the most praised companies for software updates — OnePlus — in the dust.


At present, the One UI 3.0 update has been released for over a dozen models with new devices joining the club almost every few days.

But One UI 3.0 isn’t the latest skin from Samsung. That title now goes to the One UI 3.1 skin that brings a few new features to the table.

It was introduced alongside the Samsung Galaxy S21 series in January and has since then been released for the Galaxy Tab S7 variants which got the update to One UI 3.1 based on Android 11 directly.

Earlier, we highlighted that Samsung is expected to release its new One UI 3.1 skin for the Samsung Galaxy Note 10 and Galaxy S10 series in March.

And now it appears that might indeed be the case since new test builds have popped up for the Samsung Galaxy S10 series as well as the Galaxy S20, Galaxy Note 10, Galaxy Fold, Galaxy Z Fold2, and Galaxy Z Flip.

We’ve shared the screenshots of the test builds for these devices below:

Possible One UI 3.1 test build | Galaxy Fold
Possible One UI 3.1 test build | Galaxy Note 10
Possible One UI 3.1 test build | Galaxy S10+
Possible One UI 3.1 test build | Galaxy S20
Possible One UI 3.1 test build | Galaxy Z Flip
Possible One UI 3.1 test build | Galaxy Z Fold2

At present, the latest official builds for these models are as follows:

Samsung Galaxy Fold SM-F907N | DUA4
Samsung Galaxy Note 10 SM-971N | EUA3
Samsung Galaxy S10+ SM-G975N | EUA4
Samsung Galaxy S20 SM-G981N | CUA3
Samsung Galaxy Z Flip SM-F700N | CUA1
Samsung Galaxy Z Fold2 SM-F916N | BTLL

Therefore, the bump in the first letter of the build number for each of these devices signifies a major software update.

Further, an individual has pointed out that the CheckFirm app has captured a new build for the Samsung Galaxy S10 5G SM-G977N (SKC), however, it has been listed with the Android version as 12.


Of course, don’t expect to get the update to Android 12 any time soon since Google is yet to release the upcoming Android update to developers.

Having said that, the popping up of these new test builds indicates that Samsung is indeed working on the One UI 3.1 update for the Galaxy S20 series, S10 series, Note 10 series, Fold, Z Fold 2, and Z Flip.

As usual, we will continue tracking the situation and will post an update if and when new details emerge regarding the One UI 3.0 update for either of these Samsung phones.

Meanwhile, stay tuned to our dedicated tracker to know when Samsung seeds the One UI 3.1 update to any device.
