I dont get it. Even my old s7 has a better PPI.
s20 3200 x 1440 pixels, 20:9 ratio, 566 PPI
s21 2400 x 1080 pixels, 20:9 ratio, 424 PPI
Some say "it's not noticeable bro". But for VR I assume ppi is crucial since the pixels are closer, so am I in for a disappointment? Im updating from the s7, so I assume increase in FOV will be great. Battery wise, s7 is pretty damn good, it can run 4k-5k for 4 hours. The imagine is pretty sharp specialy at 5k. I was considering buying the s21 since its on sale but im not sure anymore because of the lower PPI.
It says it can run at 120hz but im not sure if it will run VR videos at without overheating (inb4 someone claims there is not benefit if the video is not running at 120fps)
Anyway I don't get why a newer flagship phone has worse stats than the predecesor.
