Xiaomi’s HyperOS releases aren’t tied to Android releases – the company is rolling out the Android 17 update as HyperOS 3 and now it has unveiled HyperOS 4, which will most likely be based on the same core. It features a heavily reworked user interface, though.

The redesigned UI will offer more customization options for the lock screen, letting you arrange the clock and notifications as you see fit. It will also let you resize folders and group widgets. Additionally, the UI will switch seamlessly between portrait and landscape apps and will even rotate any floating apps to match.

Xiaomi has optimized the internals to speed up application loads. Based on internal testing, after 9 hours of using a phone, it will be around 18% faster in loading apps than it does with the current HyperOS 3.

There are some clever tricks that go on in the background. For example, AI will predict what resources will be needed next and preload them into RAM so that they are ready to go on the user’s command.

The company also tuned up its HDR processing algorithm – whereas an HDR photo might take 310ms to process with the old OS, the new version will do the same job in 240ms. The developers also shaved off 200ms from the camera app’s cold startup time.

Video playback has been significantly improved as well – dropped frames should be a non-issue.

Xiaomi is leveraging its in-house LLM, MiMo, to power “Super AI Assistant 2.0”. It will handle voice transcription and note organization, search your photo album, help you make travel plans, control your smart home (and smart car!), among other things. If you ask it for something more complicated, it will use the Xiaomi Super Island (the popup UI around the punch hole camera) to show you that it heard you and that it’s thinking, only showing a full-screen interface once it has an answer for you.

Xiaomi has built something called “Inspiration Ball”, which works as a pointer to give the UI some context. For example, you can drag it over an address and say “navigate here” to launch maps with a set destination. Or you can drag it over an image of a product you want and ask the AI to find it online. We might not see this in the global release, though, as its functionality overlaps with Google’s Circle to Search.

HyperOS 4 starts public beta testing tomorrow, August 14. This is probably only for China, but the devices below should be more or less the same ones that get the global beta first (we mean the ones available globally, of course).

Xiaomi is getting closer to the stable release of HyperOS 4, and more details are now emerging about the first devices in line. The Chinese behemoth has already confirmed that the REDMI K100 Pro series will be among the first models to receive the stable version. The latest rollout information also points to several other new Xiaomi and REDMI devices getting priority - mostly brand new flagships.

However, Xiaomi has not yet published a complete stable rollout calendar for all markets. This means the dates circulating online should be treated with some caution.

Summary​

  • HyperOS 4 is getting closer to its stable release, with Xiaomi and Redmi flagships expected to be among the first devices updated.
  • The Xiaomi 17 series, Redmi K90 series, and Redmi K100 Pro series are key devices in the early rollout.
  • Xiaomi is also preparing HyperOS 4 for its tablets, including the Xiaomi Pad 8 series.
  • The update brings Android 17, a new Soft Light Glass design, smoother animations, and more AI features.
  • The most important part now is Xiaomi's final global and regional rollout schedule, as update dates may differ between China, Global, and EEA devices.

What About October 15?​

A rollout date of October 15 has been reported for the first stable HyperOS 4 updates. However, Xiaomi has not yet published something concrete. For now, I would not treat October 15 as a confirmed worldwide release date.
The safer picture is that Xiaomi is preparing the stable version now, with the devices already in beta testing likely to be among the first in line.
Global and EEA users also have their own HyperOS 4 beta program. The first global and European beta devices include the Xiaomi 17 and Xiaomi 17 Ultra, while the second group includes the Xiaomi 17T, Xiaomi 17T Pro, Xiaomi 15 and Xiaomi 15 Ultra.
The stable rollout may therefore happen at different times depending on the region.

HyperOS 4 Is a Major Update​

HyperOS 4 is based on Android 17 as we all know. It brings a new visual design, smoother animations and several system changes. Xiaomi is also adding new AI features and a redesigned interface based around its Soft Light Glass design. The company is putting more focus on widgets, folders, notifications and connections between Xiaomi devices.

Nope, Xiaomi os don't allow gesture navigation on 3rd party launcher... Need to activate second space and activate gesture navigation there.

Sounds troublesome and second space is glitch from my experience IIRC.
So it's a OS issue instead of third party compatbility issue?

Yes, Xiaomi just blocked gesture navigation with 3rd party launcher. So need the second space workaround

And certain actions like opening pdfs attachment will break the gesture navigation and revert to button navigation. Yes is troublesome

That is unfortunate, have you ever left a feedback through the app to let Xiaomi know?
