Most smartphones in the market offer displays with a 60Hz refresh rate, and just in recent times, we have seen some vendors push out handsets with more fluid screens. The trend was started by gaming-centric smartphones, but now even brands like Google and OnePlus have jumped the bandwagon as their recent handsets offer a 90Hz screen. In the past, we had heard reports claiming Samsung Galaxy S20 will sport a 120Hz screen, and now the same has been reiterated.

Sammobile and Ice Universe both claim that the upcoming Galaxy S flagships will have 120Hz screens. If that’s true, the upcoming phones will be one of the first mainstream handsets to offer such a high refresh rate. As you might have heard before, a higher refresh rate makes animation and scrolling smoother, resulting in an elevated viewing experience.
