Early look at unreleased features in Huawei (华为) HarmonyOS 6.0.0.328 SP58 — Changlian (畅连) real‑time intercom and Xingdun (星盾) anti‑fraud surface

What's in the build

It has been reported that HarmonyOS 6.0.0.328 SP58 — a quietly rolling update from Huawei (华为) — contains several unannounced features, chief among them a Changlian (畅连) real‑time intercom mode and a new Xingdun (星盾) anti‑fraud suite. The build also includes smaller UX additions such as a May Day–themed limited watermark, a hidden album option in Gallery, and broader support for immersive light effects across more UI scenes. Short and visible: the update aims to blend communications, security and polish.

Changlian real‑time intercom and storage visibility

Changlian’s new intercom behaves like a digital walkie‑talkie — a tap on a prominent “microphone” control starts push‑to‑talk, supporting two‑person or multi‑party teams and live location sharing. It reportedly runs in the background and surfaces as a live window when the app is backgrounded or the phone is locked, so conversations can continue without staying in the foreground. The update also reorganizes Storage settings to show “HarmonyOS (鸿蒙)” and “System Data” with clearer breakdowns — HarmonyOS now lists models and runtime components required for on‑device intelligence, while System Data highlights logs and essential system files.

Xingdun anti‑fraud: AI plugin, call and message defense

Xingdun (星盾) is exposed under System Settings → Privacy & Security and requires users to enable it and download an AI plugin (about 39MB) on first use. The capability set is extensive: identification and blocking of unknown or high‑risk numbers, spam SMS filtering, overseas number detection, fake‑base‑station protection, video‑call and stranger‑call detection, WLAN security checks, and cross‑scenario linkage for suspicious behaviors. There’s also a “family protection” mode to share anti‑fraud guardrails with relatives. These are local, device‑oriented defenses — but it has been reported that some functions rely on AI models downloaded to the phone.

Why this matters

Why should Western readers care? HarmonyOS (鸿蒙) is Huawei’s in‑house OS developed in the wake of U.S. export controls that constrained access to some global chip and software suppliers. The company has been accelerating proprietary software features and on‑device AI to reduce reliance on third parties. New communications and anti‑fraud tools speak to two priorities for Chinese users: seamless, low‑latency interaction and protection against pervasive scams. Reportedly, Huawei is still testing and rolling out SP58 broadly, and IT之家 continues to explore additional hidden changes — expect more incremental refinements rather than a headline OS overhaul.
