In recent months, Huawei phones have sold significantly worse than before. The reason: in May, the Chinese group based in the US was blacklisted by companies whose business relations with US companies are subject to strict controls. Affected by this is also Google, the provider of the Android operating system.
These include the Huawei P30 and Mate 20 series. The Chinese smartphone maker even promises an update if cooperation with Google fails. In that case, Huawei would probably work with third-party companies to ensure an update for Android Q.
