Huawei is among the most valued Chinese companies in creating smartphones. Besides its position as the number two spot in terms of smartphone sales worldwide, Huawei is also among the leading suppliers for telecommunication equipment and a driving force in the adoption of 5G.
Until recently, Google has decided to partially cut off Huawei devices from its Android operating system that resulting in the most dramatic challenges.
Here’s what you need to know about the banning

Last week, Washington imposed a ban on the sale or transfer of American technology to Huawei, which could impact hundreds of millions of Huawei phones and tablets around the world.
Google has confirmed to comply with the US restrictions and bar Huawei from access to some core components of Android and its proprietary services.
The shocking move was made after the US Government added Huawei on the Entity list – a trade blacklist which bans the Chinese tech giant from doing business with US companies.
Existing Huawei mobile devices may not be affected

According to the source, existing Huawei devices will still operate as normal with no restrictions to Google apps like Gmail, Youtube and Play Store. The company will continue to have access to Android via the Android Open Source Project which is available for free to anyone.
While both Google and Huawei have reassured users that their phones will continue to function as normal, this could present major problems for Huawei, and apps on its phones could become unusable if it does not have access to code licensed by Google to phone makers.
What will Huawei do?

It is said that the world’s second-largest smartphone maker by sales has been preparing for years by building an operating system of its own. Its own platform named ‘HongMeng’ is currently undergoing trials and will gradually replace the Android system.
This is Huawei’s Plan B but they would prefer to work together with the ecosystems provided by Google and Microsoft. – Source
