Although the Galaxy M21 is equipped with a fairly dense 6.4-inch 2,340 x 1,080 AMOLED screen, the M22 has given up these extra pixels in order to support a faster refresh rate. Although retaining the 6.4-inch size, the M22’s display has a resolution of 1,600 x 720 and a faster 90Hz refresh rate. For gamers with limited budgets, this will be a welcome change, but carnival observers may not appreciate it as much.
