Samsung's J-lineup is being fully renovated and the 2016 badge on the model name implies meaningful updates - albeit subtle, which is understandable. After all, this is the Koreans' economy class of smartphones. But the series is obviously important enough for Samsung to even add new digits.
The J3 ( 2016) here is in a slightly different boat from its siblings. The J5 ( 2016) has its predecessor from a year ago, the same goes for the J7 ( 2016) , even the basic J1 ( 2016) and J2 ( 2016) . With no J3 from last season, Samsung is clearly enriching the selection and it's worth noting that there is a Galaxy J3 Pro in existence as well, but it seems intended for the Chinese market only. That one is technically a 2016 model too, released a mere month ago. One thing that Samsung did well to achieve is a full house of display sizes with the J series, a point that is still incredibly important. Whatever your needs and preferences may be, Samsung has you covered with a J device. They all come with the company's trademark Super AMOLED panel from as small as 4.5 WVGA in the J1, to 5.5 HD in the Galaxy J7.
