Samsung galaxy j2 - ( 2016) is the lowest priced 4 g android phone of galaxy J series, launched by samsung.
J2 is very basic featured android phone, it has 1.5 gb ram, 8 gb internal memory, average display size and average display quality with an ok battery capacity in almost 10 k rupees, in this price range we had a lot of batter options than samsung galaxy J2, such as redme 3s prime, coolpad 2.5 d mega etc.
Only the good thing of samsung J2 is its brand name with 4g connectivity which is compatible with jio 4g sim and its expandable memory option which goes upto 128 gb but again if you increase its internal memory then again you have to spend more money which overall increases the cost of mobile.
As samsung galaxy known as a reliable brand in android market thus attraction with J2 is obvous but if you want a big ram, big rom, large & good display and big battery phone other than a big brand then try some other brands.
