Huawei phones outside China have used a version of Android that comes with a package of Google services, including search, Maps, YouTube and - crucially - the Play store for downloading a range of apps.
Huawei's relationship with the United States has been anything but smooth over the previous year, but this past weekend saw the company take its biggest hit yet.
Most importantly, Huawei may lose access to Google's suite of apps and services in upcoming operating system builds, which could have a major impact on its western market.
United States internet giant Google, whose Android mobile operating system powers most of the world's smartphones, said this week it was beginning to cut ties with Huawei in light of the ban.
Google made a decision to suspend ties with Huawei after the Trump administration added the Chinese company to a trade blacklist, as the administration considers the company to be a security threat.
"The Temporary General License grants operators time to make other arrangements and the Department space to determine appropriate long-term measures for Americans and foreign telecommunications providers that now rely on Huawei equipment for critical services", Ross said.
The licence allows for the continued operation of existing networks and equipment - including software updates and patches - as well as support to existing handsets.
Huawei founder Ren Zhengfei on Tuesday shrugged off U.S. attempts to block his company's global ambitions, saying the United States underestimates the telecom giant's strength.
On Tuesday (21 May) Huawei's CEO Ren Zengfei said in an interview with Chinese state media that, "We sacrificed (the interest of) individuals and families for the sake of an ideal, to stand at the top of the world".
Question: Will Huawei phones be able to receive Android updates?
In a statement, Google said it was "complying with the order and reviewing the implications".
The Commerce Department on Monday delayed the sanctions on Huawei for 90 days, saying the additional time was needed to allow for software updates and other contractual obligations.
Ren said Huawei and Google are discussing how to respond to the ban, calling the USA firm a "highly responsible company".
Huawei is now on the receiving end of a United States government accusation that it engaged in bank fraud to obtain embargoed U.S. goods and services in Iran and move money via the worldwide banking system.
Liu said Huawei had been working on its own operating system but that he didn't have the details about when this would be ready.
The move also could assist mobile service providers in thinly populated areas of the United States, such as Wyoming and eastern OR, that purchased network equipment from Huawei in recent years. This will make selling Huawei handsets outside China close to impossible, dramatically affecting the company's ambitions to become the leading smartphone brand worldwide.
