Screen size, resolution and quality are some of the most important features to consider when choosing a smartphone.
LG V30+'s 6" P-OLED LCD is slightly larger (0.5" ) than the Sony Xperia XZ Premium Dual's 5.5" P-OLED 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).
LG V30+'s 6" screen covers 92.85% of its surface area, on the other hand Sony Xperia XZ Premium Dual" display covers only 69.65% of its total surface.
Screen size is only one side of the story, resolution is as important in most cases.
Sony Xperia XZ Premium Dual's 801ppi pixel density is significantly higher (264ppi ) than the LG V30+'s 537ppi pixel density.
