You might think that Samsung is holding back features on the Galaxy Note 20 to entice S20 owners to upgrade, but apparently that is not the case. Today, Samsung launched the One UI 2.5 Android skin for S20 devices, and the new version of the OS is not a pure cosmetic upgrade, but features that were previously exclusive to the Note 20.

The most potentially game-changing of these is wireless DeX: introduced on the Galaxy S8 in 2017, DeX ("Desktop Experience") makes compatible mobile devices act like computers by outputting to the screen, allows users to operate a large-screen desktop mode using a mouse and keyboard. As the name implies, the wireless DeX allows the handset itself to be used as a touchpad on a compatible TV. Needless to say, this is a long way from the first iteration, which required paying $150 for a dedicated dock.

Amateur filmmakers will be pleased with the improved Pro Video mode, which allows S20 owners to choose the microphone source from which they wish to record sound. They can also set the aspect ratio to 21:9 to capture more scenery (though it may look a bit odd when played back on a typical aspect ratio screen).

Other options include importing PDF files for scribbling, syncing audio recordings with written notes, and sharing Wi-Fi details between Samsung Galaxy devices.

Samsung says that rollout has already begun on compatible devices, and according to SamMobile, the 5G variant of the S20 family has begun in Italy, Hungary, Portugal, Germany, and the Netherlands. More regions and versions will be added in the coming weeks. [It's not just S20 owners who will benefit from One UI 2.5. Samsung says the update will also apply to other phones, including the Note 10, S10, S9 family, and all folding phones. But don't get too excited: in small print, Samsung emphasizes that "supported features may vary by device." In other words, don't be surprised if your creaky old S9 won't let you crank out 8K movies on camera.

Updates come wirelessly with a notification telling you when it's ready. But if you want to manually check if a new version is available, pop into your Samsung phone's settings, scroll to the bottom, and tap "Software Update."
