HyperOS 4 Explained: Xiaomi’s Next-Gen Android 17 Skin
Xiaomi HyperOS 4 is the latest generation of Xiaomi’s custom Android skin based on Android 17, offering a redesigned interface, performance improvements, and new AI-powered features, but forcing current miclaw beta testers to choose between the new system and keeping their existing AI agent tools. This is not a small iteration: Xiaomi is clearly using HyperOS 4 to redefine what its phones feel like day to day. The update is rolling out first as a beta to eligible devices, and Xiaomi is inviting existing testers to sign up. That means early adopters get the most cutting-edge Xiaomi phone update, but they also accept the most risk—especially around AI assistants. In short, HyperOS 4 is the future of Xiaomi’s software, yet it arrives with meaningful trade-offs that informed users should weigh before tapping “install”.
Design and Performance: Why HyperOS 4 Feels Like a True Upgrade
HyperOS 4 finally looks and behaves like a major Android 17 update rather than a minor polish job. Xiaomi has redesigned the user interface with a glass-inspired design language and realistic refraction effects across supported elements, producing a more modern, layered look that clearly takes cues from current liquid-style UI trends. Personalisation has moved beyond wallpapers: notifications and the clock can be rearranged, folders can be resized, and widgets can be grouped, letting power users tame their home screens instead of living with Xiaomi’s defaults. Under the surface, Xiaomi claims “applications can now open up to 18% faster after 9 hours of phone use compared with HyperOS 3,” a concrete promise that matters more than vague talk of optimization. AI-driven resource prediction that pre-loads likely-needed data into RAM should make the phone feel quicker during long days, not only right after a reboot.
Super AI Assistant 2.0 vs miclaw: The Tough Choice for Testers
The most controversial part of the Xiaomi HyperOS 4 rollout is how it treats existing miclaw beta testers. Xiaomi is inviting closed miclaw testers into the HyperOS 4 Beta, pushing the update automatically once they register through the miclaw testing program. But installing HyperOS 4 removes them from the miclaw beta, and the company has confirmed that “the miclaw AI agent is not supported on the new software.” For now, you cannot run both HyperOS 4 and miclaw on the same phone. That hurts the very users who helped Xiaomi test advanced AI features: miclaw was built to go beyond a standard chatbot, able to read intent and carry out multi-step tasks across apps and system tools. In its place, HyperOS 4 offers Super AI Assistant 2.0, powered by Xiaomi’s MiMo large language model, handling voice transcription, notes organisation, and photo search. Good, but not equivalent.
Should You Update? Opt-In, Opt-Out, and How to Switch
Whether you should install Xiaomi HyperOS 4 depends on what you value most from your Xiaomi phone update. If miclaw’s deep system integration is central to how you use your device, Xiaomi is clear: you need to stay on HyperOS 3 to keep using miclaw. If you care more about Android 17 features, fresh UI, and performance gains, HyperOS 4 is the logical step. The good news is that this beta is not a one-way door. You can exit the HyperOS 4 Beta at any time by going to Xiaomi Community, then Official, then Internal Testing Center, then My Internal Testing and selecting the exit option there. If you later change your mind, you can reapply from the same Internal Testing Center section. Xiaomi has started rolling out HyperOS 4 Beta to the first set of devices and plans to bring the stable version to all eligible devices, but it has not said when miclaw support might arrive on HyperOS 4.
