YunOS (simplified Chinese: 云OS; traditional Chinese: 雲OS; literally: "Cloud OS"), also called Aliyun OS (simplified Chinese: 阿里云; traditional Chinese: 阿里雲; pinyin: ālǐyún) is a Linux distribution designed for smartphones based on the Android Open Source Project. It is developed by AliCloud, a subsidiary of Chinese company Alibaba Group. Yun OS was released in China on July 28, 2011. The first device to run it was the K-Touch W700.
It took three years for AliCloud, involving 1,600 engineers, to develop Yun OS from the code-base of the Android Open Source Project. The company is challenging the dominant Android in China and is also looking to expand into Western markets.
As of May 2012, 1 million Aliyun-powered smartphones have been sold.
YunOS 5 ATOM was released on December 10, 2015.
Yun OS revolves around the idea of bringing cloud functionality to mobile devices. According to the company, Yun OS will feature cloud-based e-mail, Web search, weather updates, and GPS navigation tools. In addition, the Aliyun services will synchronize and store call data, text messages, and photos in the cloud for access across other devices, including personal computers. Alibaba says it will offer customers 100 GB of storage at launch. Yun OS would allow users to access applications from the Web, rather than download apps to their devices.
Relations with Android
According to Google, Aliyun is a forked but incompatible version of its open-source Android operating system. The company therefore attempted to prevent Acer Inc. from shipping an Yun OS-powered phone, arguing that Acer, a member of the Open Handset Alliance, had agreed not to produce phones running incompatible Android versions. Andy Rubin, who at the time was in charge of the Android division at Google, stated that while Yun OS is not part of the Android ecosystem, it uses runtimes, framework and various tools from Android.
Yun OS incorporates its own virtual machine, which is different from Android's Dalvik virtual machine. Yun OS' runtime environment, which is the core of the OS, consists of both its own Java virtual machine, which is different from Android’s Dalvik virtual machine, and its own cloud app engine, which supports HTML5 web applications. Yun OS uses some of the Android application framework and tools (open source) merely as a patch to allow Yun OS users to enjoy third-party apps in addition to the cloud-based Aliyun apps in our ecosystem."
From November 15, 2015, an increasing number of Chinese users found their TV applications were entirely removed from Tmall boxes, which has Yun OS embedded. The applications were removed because the Chinese State Administration of Radio had 81 TV applications on a policy violation list,. The remote application removal was executed by Tmall (an Alibaba Group company) by a silent Yun OS upgrade Not sure or built-in backdoor service on reboot (it is ambiguous as to which). There was no notification, nor any option to cancel the application removal. This behavior introduced great security concerns about Yun OS products which include mobile phones, wearable devices, TV boxes, in-car entertainment systems, among others.
