Samsung has launched an update version of j2. which is j2-6 in 2016. 1st of all the design of this phone is decent. then come to its display . j2-6 contains a 720 by 1080 pixels. which is a HD super-AMOLED display which is good . but samsung could have provide a full HD display in that range. Then come to its processor . It contains a quadcore 1.5 GHz processor which is based on cortex -A7 . that thing is not so good in processor side because ARM has produce more updated processors archetecture like A53. GPU is good which is mali-400MP2.
next come to camera portion. Rear camera is 8 MP with f/2.2 aperture which gives a decent photo with LED flas. secondary camera is 5MP with f/2.2 aperture which will a good photo but not so good compeared to other phone which comes with same budget range.
but overall performance is best and its a reliabile and durable phone which comes with this best price . And this phone gives a value for money.
