HyperOS 4 Super XiaoAI 2.0: Expert Mode, MiClaw Transition, and Android Alternatives

Current HyperOS 4 and Expert Mode Status

The current HyperOS 4 features preview should be read as a mainland-China Xiaomi feature path centered on Super XiaoAI 2.0 Expert Mode. Xiaomi's HyperOS 4 official product page presents Super XiaoAI 2.0 as based on Xiaomi MiMo and describes Expert Mode as able to perform system and application tasks within granted access. Xiaomi's published information also says the listed product details apply to mainland China and that functions vary by device and rollout.

That distinction matters for international readers. HyperOS 4 news, screenshots, or beta waves do not prove that the same Expert Mode feature is available globally, on every Xiaomi phone, or in every language. Expert Mode needs HyperOS 4, Super XiaoAI V8.1 or later, and a supported model. If your phone does not show the Expert Mode entry, treat that as an eligibility, app-version, account, region, or rollout check rather than a reason to sideload a package or switch regions.

The practical question is what the assistant can do on the phone in front of you. Check whether Super XiaoAI 2.0 understands the task, whether Expert Mode can reach the relevant Xiaomi system or app surface, and whether the proposed result is visible before higher-impact changes. Those checks matter more than a loose list of visual changes because they decide whether HyperOS 4 is useful as a system-level AI agent.

For the broader Xiaomi AI landscape around MiMo, MiMo Claw, and HyperOS AI, Xiaomi AI Ecosystem: MiMo Claw, MiMo Desktop, MiClaw, and HyperOS 4 keeps the model and ecosystem context in one place.

What the MiClaw Transition Means

MiClaw is still part of the HyperOS 4 story, but it should be placed correctly. Xiaomi described MiClaw in the HyperOS developer platform Agent ecosystem announcement as a MiMo-based system-level AI Agent. The limited closed beta began on March 6, 2026, and the invitation-based ecosystem supported Agent, Skill, and MCP development and review. That makes MiClaw a real Xiaomi system-agent test surface, not just a search rumor.

The current transition comes from Xiaomi's MiClaw closed-beta transition notice. The notice set September 21, 2026 as the date for the independent MiClaw closed beta and service to end. It also said existing testers could move into the HyperOS 4 beta route without applying again, and that the independent MiClaw test product does not run on HyperOS 4.

The product meaning is capability continuity, not a literal app merger claim. Xiaomi tested a system-agent direction through MiClaw and is carrying that direction into Super XiaoAI 2.0 Expert Mode on HyperOS 4. MiMo remains the model foundation. MiClaw remains the closed-beta agent surface. Super XiaoAI 2.0 is the assistant experience in HyperOS 4. Expert Mode is the action-oriented mode where granted access, supported tasks, and confirmation controls become practical user decisions.

Any enhanced Expert Mode benefit mentioned in the transition notice should be treated as historical and account-specific, not a current general offer. A secondary IT之家 report on the transition corroborated the September 21 independent-beta end date and distinguished continued HyperOS 3 beta use through the end date from upgrading to HyperOS 4. For a tighter status-only explanation, Xiaomi MiClaw Explained: Closed Beta, HyperOS 4, and Super XiaoAI Expert Mode explains the MiClaw timeline without turning this HyperOS 4 guide into an APK article.

Expert Mode System and App Tasks

Expert Mode matters because it moves Super XiaoAI 2.0 toward task execution on supported Xiaomi devices. Xiaomi says it can perform system and application tasks within granted access. In user terms, that means the assistant may help with supported Xiaomi phone-side steps such as finding a system surface, preparing an app task, planning a trip through supported services, or controlling compatible smart-home devices.

The official examples still depend on conditions around the task. Travel planning and navigation details can rely on relevant apps and third-party information. Smart-home control depends on supported devices, supported apps, and the user's account setup. A supported Xiaomi phone does not make every app, every service, or every connected device available to Expert Mode.

Cross-device tasks add another layer. Xiaomi says cross-device features require supported updated clients, the same Xiaomi account, nearby devices on the same network for first connection, and Expert Mode enabled on both sides where applicable. Remote file retrieval is not general remote desktop access: it needs part of the file name, compatible updated clients, and a computer that is awake, powered and networked, with the lid open and the Xiaomi service or supported XiaoAI client running.

If a phone cannot find a file, cannot see a device, or cannot run an app action, check the supported device and client, account, first-connection state, network, Expert Mode availability, and source app conditions. A task that works on one supported Xiaomi phone may require a different setting, app version, device connection, or region condition on another.

Memory, Access, Confirmation, and Deletion Controls

Super XiaoAI memory is an area to inspect on the device rather than assume from a headline. Memory may make an assistant more useful if it preserves preferences, recurring context, or prior choices, but public product pages do not by themselves establish every storage, review, or deletion behavior on every build. Check the current device for what can be saved, how it is used, and whether review or turn-off controls are available.

The memory question should be separated from the action question. Remembered context can help an assistant know that a user prefers a certain device, route, schedule, or communication style. Acting on that context is a different step. When Expert Mode uses remembered or app-supplied information to modify data, delete content, or send externally, inspect how the current build shows the target, action type, and result being requested.

Access prompts deserve the same attention. A system-level assistant may need data from apps, documents, device state, connected devices, or current screens. Look for purpose-specific access: the assistant should request the data needed for the task, identify the destination, and keep the consequence visible. If a user denies access, the workflow should explain what can still be done and what cannot continue.

Deletion and review controls should be treated as device checks. Look for places to review, edit, turn off, or remove remembered items on the actual Xiaomi build you use. Then use a low-risk preference question to see whether saved context affects later behavior and whether removing that context changes the response.

Device, Version, Region, and Rollout Checks

HyperOS 4 and Expert Mode availability should be checked through Xiaomi-controlled surfaces. Start with the official update path on the target Xiaomi phone, the current HyperOS information for the user's region, the Super XiaoAI version on the device, and any account-linked beta route. Xiaomi says functions vary by device and rollout, and the published HyperOS 4 product information applies to mainland China. Those conditions shape the real answer for every user.

Use a concrete checklist. Confirm the exact phone model, storage and battery readiness, HyperOS build, Super XiaoAI V8.1 or later, Xiaomi account, region, language, supported model status, and beta eligibility. If the Expert Mode entry is missing, check those conditions and wait for official rollout rather than treating the missing entry as a prompt to sideload files or change regions.

If the user is an existing MiClaw tester, check Xiaomi's transition instructions before upgrading because the independent MiClaw route and HyperOS 4 Expert Mode are different product surfaces. The old MiClaw test product does not continue normally on HyperOS 4, so the upgrade decision is also a product-surface decision.

After installation or beta entry, start with a low-risk Xiaomi-supported task: ask about a visible setting, prepare a travel plan using supported services, or check a compatible smart-home control. Confirm the source app, device, and account conditions before relying on the result.

The Independent Android Execution Route

HyperOS and Super XiaoAI serve Xiaomi phones. FoneClaw is an independent Android route for supported tasks across brands. That difference is useful for readers because it turns the choice into device fit, not brand noise. If your task depends on Xiaomi-system integration and your phone is eligible for the current HyperOS 4 Expert Mode route, Xiaomi's path is the natural place to evaluate first. If you want a governed Android phone-agent runtime for supported tasks outside that Xiaomi route, evaluate FoneClaw by the specific workflows you need.

FoneClaw uses a configured model for planning and governed Android tools for supported actions. A user can start with the free default model or configure a compatible model endpoint, ask for a phone task in natural language, watch visible progress, stop or retry when the path changes, recover from permission blocks, and review the final result. Approval prompts depend on Tool Approval Mode and per-tool policy, so it is not accurate to say every action always prompts in the same way. The current FoneClaw Features page describes our supported Android capability surface.

The practical comparison is integration depth versus cross-brand Android execution. Xiaomi can go deep on supported Xiaomi phones because HyperOS and Super XiaoAI live inside that ecosystem. FoneClaw gives Android users a separate route built around supported actions, current-screen context where the user selects it, capability routing, permission recovery, model prerequisites, tool prerequisites, and visible task state. For a direct decision between the current Xiaomi route and our Android phone-action route, MiClaw vs FoneClaw: Which Phone-Agent Route Fits Your Android? keeps the comparison focused.

Choose by the phone and task you actually have. Check Xiaomi eligibility if the job depends on HyperOS 4 Expert Mode, or check FoneClaw's supported Android workflows if you need a cross-brand phone-agent route with visible current task results.
