A new report has found that Samsung sold just under 600,000 units of the Galaxy S21 series in the first 4 weeks since its launch in this OEM's home country. The flagships have not done so well in this respect since the Galaxy S8 and S8 Plus debuted in 2017. Furthermore, the Galaxy A31 was found to be the best-selling Android phone in South Korea for 2020.
