Huawei Technologies has unveiled its own operating system for smartphones and other mobile devices after US sanctions limited the company's access to Google's mobile services.
The Chinese telecom giant launched HarmonyOS on Wednesday. It aims to turn around its handset business without relying on Google's popular operating platform.
Huawei had been shipping its handsets running Android.
But the United States has put the company on a trade black list, citing security threats.
That blocked the company's access to Google apps on its phones. Its overseas sales tumbled last year for the first time since 2010.
But now, Huawei appears to be betting on its expertise in the field of Internet-of-Things.
The US restriction still seems to be impacting the Chinese company. It hasn't announced any new smartphone models, as it usually does around this time of year.
