My friend is using the galaxy J2 and he is facing lot of flaws and issues with the device.First issue is with the camera.The camera is descent to take photo in day only.We cannot take nice pics when in dime light. The camera can shoot objects which are closer when we use the flash on in Night mode.
The worst part of the device is the rear speaker.One can rarly hear the phone ringing even when the phone is upside down.Again some mkv video are also not supported .It started lagging after couple of days from purchasing.
