J2 has low resoultion display 540*960 pixels(234ppi) and 4.7 inch that what you doesn’t want that poor appearance
it processor and ram is not so enough of do all your work with multitasking 1.3 GHz, Quad Core, Exynos 3475 with only 1 GB ram
you will feel lots of lag and slow speed after some times of use this phone
internal memory is also only 8 GB
camera is only 5 MP with very poor perfomance
auto falsh is working but is for name of use
sound reception is ok and as usalwal it UI with same style
overall you will feel very bad to have this.
dont go for this type of phones and it coast you around 7590 INR.
in this range you will have so many phone with will gives tou better camera and sensors.
thanks and regards
