The effect was arguably delayed by the typical annual phone cycle. Huawei is allowed to continue offering the P30 Pro and other phones that shipped before the US ban, but those devices are gradually being replaced -- the P40 Pro will be announced on March 26th. That could make Huawei's phones a much tougher sell in Europe and other regions where many users expect Google apps, even if there are alternatives like Huawei's AppGallery.

Huawei has declined to comment.

If the prediction comes to pass, it'll suggest that the US achieved one of its goals: limiting Huawei's growth. It's convinced the Chinese government can use Huawei devices for spying purposes (despite a lack of tangible public evidence), and restricting US involvement theoretically reduces the number of target devices on the market. Huawei still enjoys strong sales in its native China and other countries, but it could have a tough time challenging Apple or Samsung going forward.
