Screen size, resolution and quality are some of the most important features to consider when choosing a smartphone.
Apple iPhone XS Max's 6.5" OLED LCD is slightly larger (0.2" ) than the Samsung Galaxy S10 Plus Exynos's 6.3" Super AMOLED screen.
Besides comparing the LCD sizes, another specs that we find useful to compare is the ratio of screen area to total surface area of the phone (screen area/total surface area).
Apple iPhone XS Max LCD covers 85% of its surface which is only slightly higher then Samsung Galaxy S10 Plus Exynos's 84%.
Screen size is only one side of the story, resolution is as important in most cases.
Samsung Galaxy S10 Plus Exynos's 534ppi pixel density is significantly higher (78ppi ) than the Apple iPhone XS Max's 456ppi pixel density.
