Samsung Android 12 Tracker: Here are all the official One UI 4.0 stable and beta builds to download and install

It’s that time of year again when Google releases the new version of its mobile operating system! The stable version of Android 12 is finally here after a long few months of beta testing, and a range of smartphone makers have already announced that they plan to roll it out to their users. Being one of the largest Android OEMs, Samsung is also busy finalizing the features exclusive to its custom skin, One UI, on top of the new version of Android in preparation for an eventual rollout of One UI 4.0 via the stable channel.

When it comes to beta testing, the Korean OEM kicked off the Android 12-based One UI 4.0 beta program for the Galaxy S21 series back in September. Although Samsung has already published its Android 12 update roadmap for some regions, the company will likely bring a handful of other devices into the beta phase, including older flagships and even some mid-rangers, before the eventual stable release. The public beta initiative is being conducted through the Samsung Members app, hence Galaxy device owners are advised to check the schedule for their region by opening the app and heading to the “Notices” section.

List of Samsung phones that have received Android 12

This article covers Samsung devices that have received an Android 12 update in the form of One UI 4.0 — be it (public) beta or stable — in any region. Since none of the Galaxy devices participated in Google’s Android 12 Developer Preview program, we will solely follow Samsung’s nomenclature of build numbers in the index below for the sake of simplicity.

Here are the devices that have received at least one Android 12 build with One UI 4.0 till date. Note that the devices are sorted alphabetically for their retail name.

Generic flashing instructions are available at the bottom of this article. However, we advise users to refer to the device forums for specific flashing instructions for their device, in case there are any variations or special instructions that need to be followed.



You can find download links of One UI 4.0 public beta and stable releases below. These builds are first sorted with device names, and then according to their regions/SoC variants and release. Notably, the concept of a downgrade ROM isn’t applicable here. It is also worth mentioning that you can’t cross-flash a firmware that is intended for a Qualcomm Snapdragon SoC-based Samsung Galaxy model (e.g. the USA variant) on its Exynos-powered counterpart (e.g. the European variant) or vice-versa.

Flashing Instructions for One UI 4.0
