Here is a detail account of my experience about using SAMSUNG GALAXY J2 -
First of all let me thank samsung for bringing this budget phone at the right time of launch of 4G in india !
Now, I would like to say that I am not happy after using it. I have two samsung J2 handsets currently being used in my home but both of them are not providing healthy service ! Samsung J2 lags and gets hang frequently. I would like to say that although they have introduced a subsequent number of features yet Samsung is very far from lenovo, microsoft and redme in terms of the software quality of mobiles.
In this mobile you get 1.3 GHz quad core processor which is just not enough as per the features they have introduced in mobile. Secondly you are getting 1gb of RAM still your phone tends to be undisciplined while accepting your continuous actions and performs very badly !
Battery is of 2000 mAh capacity which will give you a good battery back up for about 18-20 hrs when mobile is used in normal way.
If you are using this mobile for gaming or video playing.trust me ! It gets so much heated that it is very difficult even to keep it in your hand !
You get 4.7 inch display screen which gives this mobile a good appearance but the display quality is not as much axpected.
J2 is equipped with rear camera of 5 mp and that of front camera as 2 mp but it is very easy to compare the quality of photographs taken from this mobile and that of lenovo 5 mp cameras !
Internal storage is of 8gb which can be extended also by using sd cards but it is very disappointing to say that sometimes mobile leaves up reading external sd cards and for correcting it you have to switch off the mobile .
Guys, if you want to buy any smartphone then plzzz go for some other phones rather than getting screwed up after buying this one !
