Xiaomi has released a small but useful update for last year’s flagship, the Xiaomi 15. The HyperOS 3.0.5.0 build rolling out in China focuses on polishing the camera app and ironing out several minor bugs rather than introducing flashy new features.
What’s new in HyperOS 3.0.5.0?
The update targets a handful of real-world annoyances. The camera app experience is the headline — Xiaomi fixed UI glitches where menu arrows wouldn’t reset their orientation after returning from Settings, a subtle but distracting issue for users who switch between portrait and landscape frequently. A few users also reported occasional failures when searching for installed apps; that problem is addressed too.
Beyond the camera and search tweaks, HyperOS 3.0.5.0 includes fixes for compatibility with some payment apps in China and other general system optimizations. These are incremental improvements: expect a smoother daily experience rather than major new functionality.

For context, HyperOS 3 (Android 16-based) was recently rolled out to Xiaomi 15 and 15 Ultra units in India, and the broader HyperOS refresh has started reaching devices like the POCO F6 Pro and the Redmi Pad 2 4G. One notable side effect reported by some users is a dip in emulation gaming performance after the HyperOS 3 upgrade — something to watch if mobile emulation is part of your routine.
And yes, Xiaomi’s ecosystem experiments continue: the company even showcased a three-drum washing machine running on the HyperOS platform, underlining how the skin is being positioned across devices beyond phones.
If you own a Xiaomi 15 in China, watch for the HyperOS 3.0.5.0 OTA and install it for a tidier camera UI and improved app compatibility. For global users, keep an eye on regional rollouts — Xiaomi tends to stagger updates by market.
