According to The Future of Smartphone Era Webinar by WitsView, a division of TrendForce, the global smartphone market has been approaching saturation, with less room for product differentiation. Thus, smartphone makers have shifted their focus to next-generation foldable models. WitsView expects the first foldable smartphone to be launched in 2019, accounting for only 0.1% in the global smartphone market. The penetration rate is estimated to reach 1.5% in 2021.
