open-source HarmonyOS phone

A Chinese development board and electronics company has launched the first-ever open-source HarmonyOS phone. Unlike Huawei phones for consumers, this device has a stable OpenHarmony 4 operating system environment exclusively for developers.

The phone is made by Shenzhen Qianhai New Silk Road Technology. This firm is majorly involved in the software and hardware technology supply chain around the HarmonyOS ecosystem. The company maker has already unveiled several OpenHarmony development boards in the past.

The purpose of this open-source HarmonyOS is to help OpenHarmony developers achieve maximum access to real-time devices while testing development practices. Therefore, it’s not designed for consumers.

The phone is currently priced at 1299 yuan and the company has started taking pre-orders until November 30, 2023. However, the shipping will start on January 30, 2024.

This open-source HarmonyOS phone launched with a 6.85-inch full HD resolution laminated LCD display. It has a front 8MP selfie camera and dual rear camera system including a 64MP main and 0.3MP macro lens setup.

The development environment of this device is powered by an octa-core Unisoc P7885 5G SoC coupled with 8GB RAM and 128GB internal storage. It’s reported that the Unisoc P7885 5G chip is built with TSMC’s 6nm EUV processing technology. It supports all scenario 5G coverage and extended operator support for fast network access.

In terms of architecture, the chip has 1 A76 large core locked at 2.7GHz, 3 large cores of A76 at 2.3GHz mid-core, and 4 A55 small cores at 2.1GHz. The chip has an integrated Mali-G57 quad-core GPU.

For connectivity, the device will offer Bluetooth 5.0, dual-band 802.11 ac ( Wi-Fi 5), and a USB 2.0 standard Type-C interface. These are important because the phone has a 4500mAh battery, which supports 18W fast wired charging and wireless reverse charging as well.
