Samsung has started rolling the second beta of One UI 4.0 based on the Android 12 for the Galaxy S21 series. The update comes three weeks after the rollout of the first beta.
One of the biggest features of the Android 12 has now come to Samsung devices via the One UI 4.0 beta 2. These are the new color themes based on the new Material You design language. This will let the users customize their designs and apply them system-wide as well as to native and third-party apps. You can choose a theme based on the colors you want on the wallpaper. As per SamMobile, the feature still has some bugs, which is understandable since the update is still in beta.
The One UI 4.0 Beta 2 also improves the input accuracy for the Samsung keyboard, adds a microphone mode in video calls. It also fixes a “problem with closing when running Secure Folder,” and improves performance.
The One UI 4.0 beta 2 update should reach you if you’ve enrolled yourself in the beta program. If you still can’t see the update, then check it manually. Go to Settings and look for the Software update menu. From here, you can check if the update has arrived for you. It is recommended to take a backup of your data before going for the beta updates since these updates are pretty unstable and can have lead to potential loss of your data.
The aforementioned Material You design language-based themes and fixes have been reported by the sleuths over at SamMobile. We will update you, once more information comes in.
