Screen size, resolution and quality are some of the most important features to consider when choosing a smartphone.
Samsung Galaxy S5's 5.1" Super AMOLED LCD is slightly larger (0.4" ) than the Apple iPhone 7's 4.7" 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).
Apple iPhone 7 and Samsung Galaxy S5 have exactly the same display coverage of 70%- so we don't have a winner here.
Screen size is only one side of the story, resolution is as important in most cases.
Samsung Galaxy S5's 432ppi pixel density is significantly higher (106ppi ) than the Apple iPhone 7's 326ppi pixel density.
