The galaxy j1 is a very typeical samsung phone, almost exactly the same size a galaxy ace 4 but with a squarer shape. It is plastic of course but the solid enough and the average , thikness and weight. Its available choice of colour white or blue. The screen size is a generous 4: 3 inches and with a resolution of 480/800 pixcel. It has a pixcel density of 217 ppi , which is typical for an entry level phone. The phone has a reasonably big battery, rated at1850 amh. That’s not huge by any means , but it’s bigger than a lot of entry level phone and should enable most user to get a couple aof days between charges especially since the phone does not really lend itself heavy use.
