As far as what form Huawei's back-up OS will take, when it will roll out and where - those details are still a bit sketchy.
Reports have placed the potential launch date of Huawei's upcoming operating system at anywhere from as early as Q3 2019 to March 2020, when the company is expected to launch its new flagship smartphones.
Not long ago, there were rumors that devices running Huawei's new OS could launch as soon as October of this year. Hongmeng will support other devices later. Sailfish OS is also known to be compatible with Android apps as well.
Samsung Galaxy Fold was originally scheduled to launch in the United States on April 26 and in the UK on May 3, but is now delayed indefinitely following a number of issues with the pliable Infinity Flex display in review units handed to U.S. media.
President Donald Trump last month offered a ray of hope to Huawei, suggesting the ban on doing business with United States firms like Google could be solved if China agrees to a new trade deal.
An executive of China's Huawei, which has been banned from working with U.S. tech firms, said on Thursday that the telecoms giant is in the process of potentially launching its "Hongmeng" operating system (OS) to replace the U.S. Android OS. That could be the reason why the USA tech giant has been lobbying for an Android exemption from the Huawei ban, arguing that the ban on Huawei will raise national security risks to the US.
In the letter to the FCC, the company objected to being banned on the grounds of national security threats. In fact, Huawei is already testing some of its devices with Aurora OS, allegedly. For all you know, it may just be a matter of building hype for a Chinese alternative to Android OS. Huawei accounted for about or 4% of the company's overall sales a year ago.
Another thing that Google has to contend with is the possibility - not all that remote, if the Sino-US trade war goes out of hand - that Beijing orders all Chinese phone makers to shun foreign software and use HongMeng as their source for the operating system.
Huawei said for the launch they would target countries with more established 5G networks.
