On December 2, 2020, we saw the first trickle of One UI 3.0 on devices with the Galaxy S20 on Verizon receiving the update. Just one day later, on December 3rd, Samsung announced that it would launch One UI 3.0 worldwide for the Galaxy S20, S20 + and S20 Ultra in the US, Korea and select global markets.

On December 8th, the T-Mobile versions of the Galaxy S20 series will receive the stable One UI 3.0 update. For other Galaxy phones, the Note 20 series, the S10 series and the foldable devices, an update will follow in January. From March, One UI 3.0 will find its way onto the phones of the Galaxy A and Galaxy M series.

From December 14th, the Galaxy Note 20 will receive the stable update One UI 3.0. The rollout starts with the AT&T models of the Note 20, but will soon be transferred to other variants and activated devices.

On December 22nd, Samsung began shipping the One UI 3.0 update for the Galaxy S10 Lite, Unlocked Note 20 models in the US, and the foldable Galaxy Z Flip 5G.

The update for the mid-range Galaxy A51 and M31 was released on December 23, with the rollout beginning in India and Korea. From December 27th, Samsung started the stable update for the Note 10 and Note 10+ in the USA

Throughout February, Samsung started moving the One UI 3.1 update to its older phones instead of the One UI 3.0. The Galaxy Note 10 Lite, Tab S6, and Galaxy A71 all got the stable version of One UI 3.1 based on Android 11 instead of One UI 3.0, and that’s great to see.

Throughout March, Samsung was delivering the One UI 3.1 update for its 2020 and 2019 flagships around the world. The Galaxy S10, Note 10 and last year’s Galaxy Fold 5G and S20 have all switched to One UI 3.1 along with the Galaxy Tab S6.

May T-Mobile began introducing the stable version One UI 3.1 for its version of the Galaxy S10 and S10 +. The unlocked models received the update earlier this year, but it’s good to see the Carrier models also switch to the latest version of One UI 3.1, albeit a little later than usual.
