As per my review I found that if we are planning to bye a Samsung mobile in the price range of 15k then I suggest you to bye a samsung galaxy on8 bcoz it has better specs than j7 even it comes with same price. on8 has 3 gb ram 16 gb onboard storage 13 mp camera exynos chipset 5’5inch super amoled with hd resolution nd a bigger batter of 3300mah it last’s for a day easy with normal usage. so every one go for on8 . Thankyou
