According to Gartner, a technology research and consulting company, smartphone sales experienced a significant rise in 2021. During the first three quarters of 2021, more than 1.04 billion smartphones were sold. These stats are nearly 88.6 million more than smartphones sold in the first nine months of 2020.

Although smartphone sales experienced a double-digit surge in the first two quarters of 2021, global smartphone sales declined in the third quarter by 6.8% annually.

The primary reason for this decline was the emergence of Covid-19. The pandemic-induced shortage of cellphone key components delayed smartphone production on a global level. As a result, sales took a severe dip from July to September.

Gartner declared the lack of components like radio frequency and power management integrated circuits to be the reason for this decline. They believe it disrupted the supply-demand equilibrium due to which end-users were burdened with limited choices at the point of sale.

Despite the global decline in smartphone sales, some smartphones have continued to sell and perform well.

In this article, we have reviewed the 7 best-selling smartphones during the first 3 quarters of 2021. So, continue reading to find one that attracts you and fulfills your requirements.

Although it launched late towards the end of 2021, Samsung did not hold back with its Galaxy A12. It enjoyed the status of being one of the most-selling budget smartphones by Samsung.
