Overview
- Xiaomi began its global stable rollout on Tuesday, Nov. 3, pushing HyperOS 4 to flagship and recent models as the first of three phased waves through December.
- Wave 1 targets 2024–2025 flagships and recent devices including the Xiaomi 17 and 15 series, Xiaomi Pad 8 models and many POCO and Redmi phones, with Wave 2 arriving in mid‑November and Wave 3 starting in December.
- HyperOS 4 is based on Android 17 and introduces a Soft Light Glass or Liquid Glass visual redesign with new lock‑screen options, larger widgets, flexible folders and improved floating‑window multitasking on tablets.
- Xiaomi highlights expanded on‑device AI via Super XiaoAi 2.0 backed by its MiMo LLM for tasks such as photo search, schedule help, smart‑home control and product recognition, though some AI features may be limited by region or hardware.
- The company cites performance and longevity gains, including faster app launches and memory preloading, but availability will vary by region, carrier and locked models so users should check System Update, back up data and expect staged delays or feature differences.
