Screen size, resolution and quality are some of the most important features to consider when choosing a smartphone.
Samsung Galaxy Amp Prime's 24 Super AMOLED and Samsung Galaxy J2 Pure's PLS screen have exactly the same LCD size of 5" so we don't have a winner here.
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 J2 Pure LCD covers 68.92% of its surface which is only slightly higher then Samsung Galaxy Amp Prime's 68.39%.
Screen size is only one side of the story, resolution is as important in most cases.
Samsung Galaxy Amp Prime's 294ppi pixel density is significantly higher (74ppi ) than the Samsung Galaxy J2 Pure's 220ppi pixel density.
