Samsung galaxy s21 has best display as compared to iphone 12 because many people’s knows that flaship smartphones of samsung have beat display out there and in comparison of displays of s21 and iphone 12. S21 supports 120hz refresh rate and this feature is not available in iPhone 12 so lastly in my opinion s21 has better display.
Galaxy S21 – 6.2-inch Dynamic AMOLED
2,400 x 1,080 at 421ppi
Adaptive 120Hz refresh rate
Iphone 12 – 6.1-inch Super Retina XDR OLED
2,532 x 1,170 resolution
HDR, True Tone
Wide color (P3)
2,000,000:1 contrast ratio
625 nits max brightness (typical); 1200 nits max brightness (HDR)
Ceramic Shield front
Just go for an iPhone because its display is far better than the S21
Iphone has more nits than S21
If you want a higher refresh rate then go for S21, but I prefer to go with the iPhone 12
Samsung has been the leading company of producing amoled screens and has been till now. The s21 comes with 6.2-inch Dynamic AMOLED display, with its FHD resolution of 2400×1080, sports an adaptive refresh rate that can range from 48Hz all the way up to 120Hz.
while the iPhone 12 just packs 6.1-inch Super Retina XDR OLED display with a slightly sharper 2532×1170 resolution. Both produce very beautiful colour display but the s21 has more natural colors and is brighter than the iPhone 12. In my perspective the iPhone screen which is basically another Samsung screen does well alright but the display on the s21 is one of a kind.
