One UI 2 (Android 10): which Galaxy phones and tablets have it

Updated November 4, 2022

One UI 2 is an earlier One UI: its successor One UI 3 has replaced it on the models that were still supported. It is based on Android 10. In our firmware archive 491 Galaxy models have builds with it: 409 phones and 82 tablets. The first build was for Galaxy A9 (2018) (SM-A920F), dated 2019-10-29.

One UI 2.0, 2.1 and 2.5 share Android 10, so this list includes all of them. Dates are build dates of the first firmware for each model; the update usually reaches phones in the first region days to a few weeks after that date, other regions later.

Getting One UI 2 before the update arrives

Samsung releases a major update region by region, and carrier-locked US models (SM-xxxU) often get it weeks after the unlocked international ones (SM-xxxB). If your model is in the list above but your phone still says it is up to date, the build exists but has not been pushed to your CSC yet. Two ways around it: wait, or install the official firmware yourself. The second needs a Windows PC and Odin, and the manual update guide walks through it, including how to keep your data with HOME_CSC.

Going back after the update is often impossible. Major updates often come with a higher bootloader binary, and Odin refuses older builds with "SW REV CHECK FAIL". See downgrading Samsung firmware before you count on a way back.
