One UI 4.0 isn’t new news. Samsung will begin testing One UI 4.0 for the Galaxy S series in July, according to a report from Ice Universe last month. Also, according to Ice Universe, the Galaxy Z Fold 3 will come with One UI 3.1.1 out of the gate. In case you missed it, Samsung is expected to unveil the Galaxy Z Fold 3 and Galaxy Z Flip 3 at its Galaxy Unpacked event next month.

Starting the beta program early also means that Galaxy smartphones may get a taste of Android 12 sooner than planned. Google plans to release Android 12 later this year, ideally around September. We’ll have to wait till Samsung finalizes and unveils all of the OneUI 4.0 features. Meanwhile, you can read our post to learn about the finest Android 12 features as well as a list of Samsung Galaxy smartphones that are expected to receive the One UI 4.0 upgrade.
