Samsung's One UI 3.0 interface, based on Android 11, appeared with the new Galaxy S21 released last month. However, Samsung has not finished the software update, and this time the foldable phone is the big beneficiary.

The One UI 3.1 update has been released and is now available for Samsung phones, including the Galaxy Z Fold 2 and Galaxy Z Flip. It is worth noting that the latest update has a number of improvements specifically targeted at foldable devices, according to Samsung.

Among the highlights for users of foldable phones are improvements to Multi-Active Windows, a multitasking feature. By using Multi-Active Windows to run multiple apps, users will be able to do things like search for something while watching a video. [One UI 3.1 allows up to three different multi-active windows on the main screen of a folding phone. It also adds the ability to launch a multi-active window from the Notification Center in the Quick Panel.

One UI 3.1 also simplifies the process of turning off the screen by adding the Palm Touch to Turn Off Screen feature. With this feature enabled, a simple palm touch or double tap can put either screen of the Galaxy Z Fold 2 to sleep.

With the update, Samsung's foldable device also offers more flexibility with the camera: when you choose to shoot in Flex mode, you can change the placement of the controls so you can start shooting more comfortably. Samsung also implemented a share and delete button in the Flex mode preview mode.

Video calling in Flex mode has also been improved; Z Fold 2 users can now fill the top half of the display with the video stream of the connected party when making a call in Flex mode. [One UI 3.1 also applies to Galaxy S10, Note 20, and Note 20 models

With this update's focus on foldable features, Samsung is making devices like the Galaxy Z Fold 2 and Galaxy Z Flip more main stream, indicating that the company is quite serious about making it a main stream. Earlier this year, Samsung's TM Roh promised that the company would make foldable devices "more accessible to everyone" during 2021. Just last week, Samsung launched a 100-day trial of foldable phones to get more people to consider them.
