Samsung kicked off the One UI 3.0 public beta program for the Galaxy S20 series early last month. A few weeks after the update started rolling out to Galaxy S20 users, the company expanded the beta program to include Galaxy Note 20 series devices. Then, earlier this month, Samsung announced that it would be expanding the One UI 3.0 beta program to more devices, including the Galaxy Z Fold 2, Galaxy Z Flip 5G, the Galaxy S10 series, and the Galaxy Note 10 series. As promised, the company has now opened the One UI 3.0 beta program for the Galaxy S10 series in South Korea, India, and the UK.

According to recent posts on Samsung's Community forums, the first One UI 3.0 beta build has now started rolling out to Exynos variants of the Galaxy S10, Galaxy S10 5G, Galaxy S10+, and the Galaxy S10e in India and South Korea. The build is based on Android 11, and it comes with the Android security patches for October 2020. The beta program is also live in the UK, according to a recent post from Reddit user u/OMGITSYOURMUM.
