Overall, Gartner finds that global sales of smartphones to end users declined 2.7% in the first quarter of 2019, totaling 373 million units, as slowing innovation in flagship smartphones and rising prices continued to extend replacement cycles.

The report shows continued growth for Huawei all regions, especially Europe and Greater China, where its smartphone sales grew by 69% and 33%, respectively.
