Screen size, resolution and quality are some of the most important features to consider when choosing a smartphone.
Samsung Galaxy A9 (2018)'s 6.3" Super AMOLED LCD is slightly larger (0.6" ) than the LG G6's 5.7" 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).
Samsung Galaxy A9 (2018) LCD covers 81% of its surface which is only slightly higher then LG G6's 80%.
Screen size is only one side of the story, resolution is as important in most cases.
LG G6's 565ppi pixel density is significantly higher (173ppi ) than the Samsung Galaxy A9 (2018)'s 392ppi pixel density.
