HyperOS 4 Setup Leak Reveals 10 New Features and Glass Design

A leaked HyperOS 4 setup screen has exposed Xiaomi’s planned onboarding flow, along with a list of ten major features tied to the update. The files directly reference “Xiaomi HyperOS 4” and divide several features by device class, with some Glass effects marked exclusively for flagship models and the Q18. The leak also backs up earlier reports about Xiaomi’s new Glass interface, AI features, widget stacking, and redesigned system apps.

The leaked configuration includes the following onboarding text:

HyperOS 4 Setup Lists 10 New Features

The leaked onboarding package contains ten distinct sections:

• 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
• New AI Notes
• Xiaomi Intelligent Input Method

This matters because the package goes beyond concept images. It includes internal labels describing exactly how Xiaomi plans to present HyperOS 4 features during the setup process.

Glass Features Are Clearly Split by Hardware

One of the most notable entries is “Glass Material,” which supports earlier leaked source-code findings showing that HyperOS 4’s full Liquid Glass rendering won’t be available on every chipset.

Previous code discoveries pointed to support limited to:

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

The new setup files add another useful clue: Xiaomi itself appears to separate Glass features from the basic HyperOS 4 experience. In other words, a device could receive HyperOS 4 without gaining access to every advanced Glass effect.

Previous coverage looked at Xiaomi’s HyperOS 4 Liquid Glass design direction and the HyperOS 4 V8 Launcher leak. These new onboarding files provide stronger evidence that Glass effects are part of the actual HyperOS 4 feature set, rather than existing only as an experimental launcher design.

New Lock Screen Uses the Glass Interface

The leaked screenshots reveal a major lock-screen redesign. Large transparent clock layouts can sit directly over photos and wallpapers. Some styles feature oversized vertical numbers, while others pair the clock with translucent notification cards.

The setup file specifically labels the new lock-screen experience as “Glass,” suggesting the complete Glass version of the lock screen may be reserved for higher-end devices. The notification design also lines up with earlier reports about stacked lock-screen notifications. Rather than several separate cards taking up screen space, notifications can appear layered inside a single Glass container.

Widget Stacking Is Also a Flagship Glass Feature

HyperOS 4 will introduce desktop widget stacking, according to the leaked setup package.

The screenshots show several redesigned widgets, including:

• Weather
• Clock
• Calendar
• Music controls
• Brightness and volume controls
• Search

Many of these widgets use translucent surfaces that reflect or blur the wallpaper underneath them.

The internal entry for widget stacking again lists both “flagship” and “Glass,” indicating that the full visual implementation may depend on supported hardware, even if a simpler version of the widget functionality reaches more devices broadly. This feature is already usable through the leaked HyperOS Launcher V8.

Large Folders Get Size Switching

HyperOS 4 also appears set to expand Xiaomi’s large folder system. The setup files reference folder size switching, and the screenshots show compact folders capable of displaying multiple system applications directly on the home screen. Earlier HyperOS 4 V8 Launcher builds had already demonstrated more flexible folder controls, and this new setup leak indicates Xiaomi plans to present folder resizing as one of the update’s main features.

Xiaomi HyperConnect Device Center Gets a Full Glass Redesign

Another screenshot reveals the redesigned Xiaomi HyperConnect device center. Connected products appear as large translucent cards, with examples including:

• Xiaomi Buds
• Xiaomi Pad
• Xiaomi SU7
• Xiaomi Watch
• Air conditioner
• Smart camera

Each card blends with colors pulled from the background, making this one of the clearest examples of the new Glass material system shown in the leak. The setup package refers to this feature as the “New Fusion Device Center,” Xiaomi’s term for its cross-device control interface.

Super XiaoAI Gets a New Floating Interface

HyperOS 4 also includes a major Super XiaoAI redesign. One screenshot shows the assistant appearing as a floating interface over the home screen, while another shows a compact status element near the top of the display while the assistant processes a request. This lines up with an earlier Digital Chat Station report describing an AI assistant floating island, compared conceptually to an AI Siri-style interface.

The screenshots also reveal different AI processing modes, including:

• Automatic
• Fast
• Expert

The leaked setup package separately lists Super XiaoAI Expert Mode, suggesting the assistant may let users choose how deeply it processes a given task.

Expert Mode Can Perform More Complex Tasks

The Expert Mode screenshot offers another clue about Xiaomi’s AI direction. In the example, a user asks Super XiaoAI to create a recurring task that collects product information every week and sends the result at a scheduled time. The assistant then generates an AI task card with a weekly schedule attached. This suggests Expert Mode may extend beyond simple question answering to handle multi-step actions across applications.

That said, the screenshots don’t confirm which apps, regions, or languages will support this functionality at launch.

AI Notes Gets Meeting Summaries and Smart Actions

HyperOS 4’s Notes app is also receiving deeper AI integration. The screenshots show:

• Meeting recording
• AI meeting summaries
• AI-generated notes
• Task extraction
• Podcast generation
• Contextual AI questions

One example shows a meeting note paired with an audio recording and an automatically generated summary. Another interface lets users ask questions about stored notes, including requests to recall important recent events or summarize previous meetings. This appears to go beyond a simple visual refresh, with AI features integrated directly into the Notes workflow itself.

Xiaomi Intelligent Input Method Adds AI Writing Tools

The leaked setup package also lists a new Xiaomi Intelligent Input Method. One screenshot shows an AI toolbar positioned above the keyboard, offering options such as:

• AI translation
• Voice input
• Automatic text polishing
• Personalized AI rewriting

This suggests HyperOS 4 will bring system-level AI writing tools directly into text input, rather than requiring users to open a separate assistant app to access them.

HyperOS 4 Could Arrive Very Soon

Based on the current development stage and the appearance of a finished onboarding package, HyperOS 4 now looks much closer to release than earlier leaks suggested. Current information points to a possible launch window at the end of August or in early September 2026. That timing remains unofficial, so it should be treated as an expected window rather than a confirmed date.

The setup package matters because it brings together many previously separate leaks in one place: Glass materials, lock-screen changes, stacked widgets, folder customization, AI input tools, AI Notes, Super XiaoAI, and the redesigned HyperConnect device center.
