Technological advancements tend to shake the industry every now and then and the mobile phone industry is no different. Every year brings new trends and some exciting features with every flagship released. Some of the changes are incremental but some changes really set the standards and drive the smartphone industry to a whole new level. Compared to 2020, 2021 is a completely different story. Every manufacturer as of now is focused to add the number of cameras to their phones having multiple focal lengths. Samsung and Apple will more likely follow the OnePlus and incorporate the promotion displays of 120Hz. We will more likely see foldable devices from many other players and 5G phones will become more common as the technology gets more coverage with the passage of time.
