Shortly after Huawei was blacklisted by the US government, Google announced that it was revoking the company's access to its Android service. Bloomberg reported that Google had cut off supply to hardware as well as software.

The news was a huge blow to Huawei, as all of its phones a run on Google's Android operating system. It means millions of Huawei customers could lose access to security updates and suffer other disruption.

After the Department of Commerce granted Huawei a 90-day reprieve before the ban fully kicks in, Google said it had put its Android suspension on hold. But at the moment, this is simply delaying the inevitable.

Huawei has been working on building its own operating system as a "plan B" for years, and though little is known about it, an executive told CNBC it could be ready for China by this fall and for the rest of the world in the first or second quarter of 2020.

The Financial Times reported that Google executives have been lobbying the Department of Commerce to gain either a second temporary license or a permanent exemption from the ban. Their argument is that if Huawei were forced to deploy its own hybrid version of Android it would be more likely to contain bugs and therefore be more vulnerable to attack — posing a national security risk.
