Samsung is in number 2 position in Indian smartphone market but their some android mobiles are too laggy to be used. For an example Samsung galaxy j2 is the worst phone I have used. The reason is -
1) its bad prossecor which is so laggy that it often bricks the mobile, I found that some apps are not working properly or not opening.
2) its 2600 mah battery hardly bears myself for 2.5 hours which is very poor
3) I found heavy heating problem during gaming and also lagging issue
4) the 8 mp camera is not taking good pictures but in pictures they are whitish.
5) the only good thing I like in this phone is its screen, which is bright and clear
my experiance with this phone is not good enough.
I recomend you not to buy this product and waste your money.
thank you.
