OpenHarmony 7.0 Beta 1 Launches Ahead of HarmonyOS 7 Debut at HDC 2026

A few hours before Huawei officially unveiled HarmonyOS 7.0 at HDC 2026, the company quietly dropped OpenHarmony 7.0 Beta 1 — a pre-release build that had first surfaced three weeks earlier and has now been formally released as a public testing framework for device makers and developers.

OpenHarmony serves as the open-source foundation that device manufacturers and software developers use to build custom operating systems for smartphones, tablets, and IoT devices. This Beta 1 release brings a range of new capabilities spanning ArkUI, ArkWeb, ArkTS, camera management, media handling, and more.

On the UI and application side, the update introduces dynamic layout containers, global reuse of custom components, and a redesigned window management system. Notification handling gets more flexibility with support for custom notification ringtones, while granular per-app controls have also been expanded. ArkWeb receives optimized web page control capabilities and a kernel upgrade to Chromium 144, along with URL whitelist control support.
