Screen size, resolution and quality are some of the most important features to consider when choosing a smartphone.
Xiaomi Mi 10 Ultra's 6.67" AMOLED LCD is slightly larger (0.17" ) than the Oppo A72 5G's 6.5" IPS 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).
Xiaomi Mi 10 Ultra LCD covers 90% of its surface which is only slightly higher then Oppo A72 5G's 83%.
Screen size is only one side of the story, resolution is as important in most cases.
Oppo A72 5G's 405ppi pixel density is only slightly higher (19ppi ) than the Xiaomi Mi 10 Ultra's 386ppi pixel density.
