Samsung , the most trusted and leading mobile brand in indian market , afew years back launched a budget smartphone called Galaxy J2 2015 which is not as much worthy at ifs price range .
Since the phone comes with 1.3 Ghz quadcore samsung exynos 3475 chip set with 1 GB of RAM which is quiet good but the processor is not as much as powerful to resist the load of the phone throughout.
As result in its battery faliure, the battery life drop to 15 to 25% due to the processor used in the phone is not efficient and effictive at this price range .
The phone runs with android 5.1 lollipop which doesn’t get any update in future.
The cameras are average as phone got 5mp rear focus camera with flash and a 2mp front shooter.
Phone comes with 8 GB internal storage which can be expand upto 128 GB which is quiet good.
Although phone have commonly all types of sensors and a 3.5mm jack .
So in my opinion the phone is totally useless and not at all worthy at that price range . You can buy another good phone at that price range .
