As everyone knows Samsung J series the older ones were having lot of issues they use to drain fast and use to hang a lot. But then they came up with the 2016 edition and every J series phone were replaced by the new ones. And I have a Samsung Galaxy J7 2016 edition bow and it’s way better than the older handset. The battery is 3100mah front flash and all the bugs are removed and it’s faster than the old one it does not hang at all. Camera is very nice and they have Marshmallow version already updated in it.
