Apart from HarmonyOS, which HUAWEI distributes to mobile devices, there is the OpenHarmony operating system, which does not contain Android source codes.
HUAWEI has been developing its own operating system independently of Android since 2019. Until 2020 there were only leaks, then HarmonyOS 2.0 development began, which was gradually rolled out to users. The problems with the US government and the ensuing embargoes prompt HUAWEI to produce its own solutions. OpenHarmony, the heart of HarmonyOS, is, as its name suggests, open source and continues to be developed.
HarmonyOS open source has been used for a long time. Current HUAWEI smartwatch models use a custom version of OpenHarmony. HUAWEI Watch 3 series includes HarmonyOS based on Android, APK applications can be installed on this model using third-party tools. The HUAWEI Watch GT 3 series, on the other hand, has a HarmonyOS which is very similar to the HarmonyOS on the Watch 3, but is completely independent from Android, running the LiteOS core.
Android-based HarmonyOS, which is used in smartphones, tablets and smartwatches, includes OpenHarmony. The HUAWEI P50 series, for example, comes with HarmonyOS 2.0.1 based on Android 11. Even if you download and extract the phone software, you won’t find any HarmonyOS items. The open-source HarmonyOS codes are outside the Android partition.
Finding out if HarmonyOS with Android 11 has the OpenHarmony runtime is pretty straightforward: a simple app called oh_info shows the device model, OpenHarmony version, API level, and more.
It is unclear where the app named “oh_info” comes from, which displays details of OpenHarmony on the device. It is not the one that was officially released by HUAWEI, but it is an app that was leaked by HUAWEI testers. OpenHarmony versions 1.0, 1.1 and 2.0 are development versions and not much is known about them. However, in OpenHarmony 2.2 and beyond there have been some serious changes.
The latest version, Open Harmony 3.1, offers many new features over previous versions. Earlier versions are for iOT devices and are quite useless for end users. With version 3.1, serious changes and innovations have been made to the user interface, which is now more useful and beautiful. The system interface now supports tablet and phone screen formats. The control panel has been improved and given a new look. The widget design also resembles Android-based HarmonyOS.
In addition to HarmonyOS used in smartphones and tablets, open source HarmonyOS The subsystem brought support for Harmony application packages. Application packages ending with “.hap” and “.app” are not used worldwide, but their development in China has increased sharply. Some Chinese app developers have started adopting the new app extension and uploading “.hap” apps to HUAWEI AppGallery
