Surge OS 3 (澎湐 OS 3) progress: gray-and-white rear‑display photo preview on Xiaomi (小米) 17 Pro Max reportedly fixed

Latest update

It has been reported that a Xiaomi employee posted in the company’s official community outlining recent optimization progress for Surge OS 3 (澎湃 OS 3). The post singled out a fix for a problem in build 3.0.305.0 where the Xiaomi 17 Pro Max (小米 17 Pro Max) would show a gray‑and‑white preview after taking photos with the rear display. Other model‑specific issues were also listed as addressed or under remediation.

What was changed

According to the report, fixes and optimizations cover input‑method and voice‑to‑text problems on the 17 Pro and 17 Pro Max (some in 3.0.305.4), a WeChat floating‑window hang on the 17 Pro (3.0.304.0), automatic brightness on the Xiaomi 15 Ultra (3.0.301.0), Super Xiao‑Ai activation on the Xiaomi 15, and a Xiao‑Ai course schedule crash on the Redmi K90 Pro Max (红米 K90 Pro Max, 3.0.303.0). The company’s note paired each issue with the build in which the fix or mitigation was applied.

Broader context and implications

This update comes as Xiaomi phases out MIUI. Xiaomi’s official Weibo account says MIUI has “completed the handover” to Surge OS, and the company reportedly upgraded millions of devices while listing many others as no longer supported — though it says necessary security patches will continue. Why does this matter? For users it changes upgrade expectations; for the industry it highlights a consolidation of smartphone software in China. It has been reported that the transition also sits against a backdrop of increased focus on domestic software resilience amid broader geopolitical and supply‑chain tensions.
