I purchased this Samsung galaxy j2 it has some features mentioned like 5MP primary camera with auto focus, LED flash, geotagging, touch focus, face detection and 2MP front facing camera4.7-inch ( 11.93 centimeters) Super AMOLED capacitive touchscreen with 540 x 960 pixels resolution, 234 ppi pixel density and 16M color supportAndroid v5.1.1 Lollipop operating system with 1.3GHz Cortex-A7 quad core processor, 2000mAH lithium-ion battery but all this features are waste as it doesn't function properly when done multitasking if you open 2 or 3 apps at same time it will started lagging the screen freezes while gaming wifi settings is poor it doesn't detect connections easily waste
