Screen size, resolution and quality are some of the most important features to consider when choosing a smartphone.
Samsung Galaxy J3's 5" Super AMOLED screen is significantly larger (0.7" ) than the Samsung Galaxy J1's 4.3" TFT 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 J3's 5" screen covers 70% of its surface area, on the other hand Samsung Galaxy J1" display covers only 60% of its total surface.
Screen size is only one side of the story, resolution is as important in most cases.
Samsung Galaxy J3's 294ppi pixel density is significantly higher (77ppi ) than the Samsung Galaxy J1's 217ppi pixel density.
