One UI 4.0 features you can test on the beta

Samsung has announced what to look for in the One Ui 4.0 beta, and the central and focal point of the new skin is customization. This somewhat reflects Android 12's focus as well, as the skin is based on the new OS update by Google. With the new skin, users will be getting a lot of theme options that will adjust the look and the functionality of the devices. Things like the home screen, icons, notifications will be customizable alongside wallpapers and other aspects of the phone experience.

It seems that these new customization options are tied to Android 12's Material You redesign, which is also centered on giving a multitude of customization options and a new pleasant viewing experience on your smartphone.



On top of that, users will be getting a more diverse array of emojis in one place, and you can easily navigate them.

In terms of other features One UI 4.0 will bring, some new privacy and protection features are coming. Many of these features are core features of Android 12, for example, inducators that alert you an app is using your camera or microphone. But the improvements don't just stop there. One UI4 4 expands on the Android 12's permission options, and allows you to view permission history not only for the last 24 hours, but for the last seven days as well.


One UI 4 will come with camera updates and some new multitasking and sharing features.
