Xiaomi HyperOS 4 Beta: Leaked Features, Liquid Glass Restrictions, and Full Rollout Timeline

Xiaomi's next major OS update, HyperOS 4, is now in beta in China. Based on extensive leaks from tipsters like CoolAPK and Digital Chat Station, as well as code teardowns and leaked onboarding files, we have a clear picture of what the update includes, which devices get the flashiest new visuals, and when you can expect to install it. None of this is official from Xiaomi yet, so treat every date and feature as unconfirmed until the company makes its own announcement.

Ten Feature Categories Leaked from Onboarding Files

A leaked HyperOS 4 setup screen — the onboarding sequence you see when first turning on a device — exposed ten distinct feature categories Xiaomi plans to highlight :

Feature Category	Availability
Basic Experience	All models
Glass Material	Flagships and Fold 5 only
New Lock Screen Experience	Flagship, Glass
Desktop Widget Stacking	Flagship, Glass
Folder Size Switching	Flagship, Glass
New Xiaomi HyperConnect Device Center	Glass
Super XiaoAI Interaction Redesign	Flagship, Glass
Super XiaoAI Expert Mode	Not specified
New AI Notes (meeting summaries)	Not specified
Xiaomi Intelligent Input Method (AI writing tools)	Not specified

This list confirms Xiaomi plans to gate specific visual and AI features by device tier. A phone can receive the HyperOS 4 update without the new Glass interface .

Liquid Glass: The Headliner Feature with Strict Hardware Requirements

The full Liquid Glass visual system — GPU-accelerated real-time light field rendering, dynamic depth and refraction calculations, and redesigned 2.5D icons — is enabled only on devices with the following chipsets :

• Snapdragon 8 Elite or newer
• Dimensity 9500 or newer
• XRING O1
• XRING O3

Previous-generation flagship chipsets (including older Dimensity parts) do not appear in the leaked whitelist . Devices with those processors may receive a simplified version of the glass effects or none at all .

The leaked code suggests Liquid Glass is not a simple theme or transparency toggle — it uses the NPU and GPU simultaneously, which explains the strict chip-level restriction .

Beyond Liquid Glass, other reported visual changes include a rewritten launcher in Rust and Flutter (marking a full break from the old MIUI codebase), two glass styles named Clear and Soft, thicker status bar icons, a shorter gesture navigation bar, and updated system app icons .

Rollout Timeline: Beta Now, Stable in October for Global Users

Leaked schedules indicate four key beta milestones in China, all times China Standard Time :

• August 5, 10:00 AM — Preheating (promotional campaign) begins
• August 5, 3:00 PM — Beta applications open
• August 6, 3:00 PM — Official HyperOS 4 launch event
• August 7, 10:00 AM — First batch of beta builds rolls out

Reports suggest the first beta testers in China will be Xiaomi 17 series and Redmi K90 users .

For the stable release, the consensus from multiple tipsters and industry sources is:

• China stable: Expected in August 2026, likely debuting alongside the Xiaomi 18 series or possibly the Mix Fold 5
• Global stable: Expected around October 2026, starting with the Xiaomi 17 and 15 series
• Update base: Android 17

Some sources caution that the stable release could slip to September or October depending on beta stability .

Important Caveats

All information in this article is based on leaks and unofficial tipster reports. Xiaomi has not officially confirmed the feature set, supported chipsets, or release dates. The actual public rollout may differ significantly. Xiaomi President Lu Weibing has confirmed a "new generation OS" is coming in July or August 2026, but has not provided specific details .
