More good news from a smartphone market currently rebounding from the far reaching impacts of the pandemic. New numbers from Canalys put global shipments for Q1 2021 at 27% above where they were the same time last year.

The industry was hit early and hit hard by Covid-19. The first quarter saw company running into serious supply chain issues as the pandemic first hit China and parts of Asia where most manufacturing occurs. Following that, demand began to slow, as fewer people were interested in buying mobile devices, coupled with broader economic and job impacts.
