Samsung announces One UI Book 4: It's One UI but for Windows

Samsung intends to make the visual experience of its Windows- and Android-based devices more cohesive.

Published onOctober 26, 2021

  • At SDC 2021, Samsung launched One UI Book 4.
  • Like One UI 4 for Android devices, this version works on Samsung Galaxy laptops.
  • Samsung intends to make the visual experience more cohesive when using its Android or Windows products.

At the Samsung Developers Conference (SDC) happening right now, we’ve already seen Samsung announce some significant smart home news. Now, though, we have some news related to Samsung’s line of laptops that is pretty unexpected.

Samsung will soon roll out a Windows skin to be known as One UI Book 4 (h/t Avi Greengart). Like the Android skin known as One UI 4, the Windows-based version will change around the look of Windows apps to better fit the Samsung aesthetic. It will also make the visual experience of using a Samsung laptop better match the experience of using a Samsung smartphone.

This is yet another step Samsung is taking to integrate more of Microsoft within its systems. We’ve already seen Samsung pre-install Microsoft apps on its phones as well as make early adoption of protocols for your Windows PC and Android phone to work together.

One UI Book 4 will be available for the Galaxy Book Pro 360, Galaxy Book Pro, Galaxy Book Flex 2, Galaxy Book, and Galaxy Book Odyssey. Presumably, it would likely be available for future Galaxy laptops as well.

At this stage, not much is known about how One UI Book 4 will look or how much of Windows it would change. One UI itself deviates quite far from stock Android, but Windows is not an open-source system, so Samsung can only change so much. We’ll need to wait and see how this pans out.
