HarmonyOS History

A source-linked history separating HarmonyOS platform origins from confirmed version-level AI changes.

6 formal versions1 separate previewOfficial sources prioritized

Timeline scope: The formal release sequence covers HarmonyOS 1 through 6. HarmonyOS 7 is listed separately because the selected official evidence confirms a Developer Beta, not a stable release.

Evidence levels show how strongly the currently linked material supports a record. They do not rate product quality or general availability.

System lineage

HarmonyOS and EMUI are related, but not a simple rename

Huawei introduced HarmonyOS 1.0 for smart-screen deployment before the large phone migration. HarmonyOS 2 then expanded to smartphones and explicitly compared its experience with the previous EMUI generation. Huawei also maintains a separate global EMUI product page, so the transition should not be reduced to a universal one-step rename.

HarmonyOS 7 Developer Beta

Agent Framework 2.0 Developer Beta

Jun 12, 2026

Huawei's official HDC record confirms a HarmonyOS 7 Developer Beta and an upgraded agent architecture, but not a stable HarmonyOS 7 release.

New in this version

Agent architecture upgrade

Huawei described HarmonyOS Agent Framework 2.0 and deeper agent integration as Developer Beta capabilities. [1]

More proactive agent behavior

The official HDC material positions the preview around more proactive, system-level agent assistance. [1]

Compared with the previous version

The Developer Beta advances the HarmonyOS 6 agent direction with a second-generation framework, but it is not a stable-release comparison. [2][1]

HarmonyOS 2

Phone migration at scale

Jun 2, 2021

HarmonyOS 2 marked Huawei's large-scale expansion to smartphones, tablets, watches, and other connected products in China.

New in this version

Phone migration at scale

Huawei moved HarmonyOS into a large smartphone upgrade program and used the previous EMUI generation as a direct comparison point. [1]

EMUI remained a distinct global line

Huawei's global consumer site continues to publish an official EMUI product page, which limits any claim that every EMUI product was universally renamed HarmonyOS. [2]

AI milestone not confirmed

The selected official sources do not confirm a version-level AI change for this release.

Compared with the previous version

Compared with HarmonyOS 1's smart-screen starting point, HarmonyOS 2 established the large-scale mobile migration and upgrade phase. [3][1]

HarmonyOS 1

Distributed OS foundation

Aug 9, 2019

Huawei introduced HarmonyOS as a distributed operating system and identified smart screens as its first deployment category.

New in this version

Platform origin

The first official deployment path covered smart screens before later expansion to other device categories; this is not evidence that HarmonyOS 1 began as a phone-wide EMUI replacement. [1]

AI milestone not confirmed

The selected official sources do not confirm a version-level AI change for this release.

Starting point

This is the starting point of this formal sequence; no earlier release in this history is compared.

How to read this history

  • Most version-specific evidence in this history comes from Huawei's China-region pages.
  • Feature access can vary by region, device, software version, account, language, and later software updates.
  • Huawei's descriptions confirm vendor claims and release positioning; they are not independent product tests or proof of worldwide availability.
  • An AI change appears only when the selected official source states a version-specific capability. General descriptions such as smart experience or cross-device collaboration are not treated as AI evidence.
