Screen size, resolution and quality are some of the most important features to consider when choosing a smartphone.
Huawei Mate 30 RS's 6.53" Flex OLED screen is significantly larger (1.03" ) than the Oppo R7s's 5.5" 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).
Huawei Mate 30 RS LCD covers 94% of its surface which is only slightly higher then Oppo R7s's 70%.
Screen size is only one side of the story, resolution is as important in most cases.
Huawei Mate 30 RS's 409ppi pixel density is only slightly higher (8ppi ) than the Oppo R7s's 401ppi pixel density.
