A:Answer for the USA version of the 2016 which is on the Tmobile, Boost, Virgin Mobile and Metro Pcs sites this is the same phone: same processor, ram, storage, single sims, sd card slot, only white color selection and size across the board.
the usa 2016 appears to be an upgraded international 2015. the size appears close, the back appears similar.
Yeah, cause the confusion comes with the comparison to the international j7 versions for 2015, 2016 with the USA 2016 version. there was no USA 2015 version. so the comparisons are with the International versions and they all differ. The international 2015 is similar in size and looks like the USA 2016 yet they differ on the inside. the international 2015 is smaller in processor and ram it has dual sims/sd slot and comes in 3 colors. The 2, 2016 versions the International comes in 3 colors, is smaller in size and has the biggest processor and all the goodies. The USA 2016 version is what you read on the current carrier sites. faster processor than the international 2015, more ram, storage, single sims, sd slot color only in white. depending on the source the 2015 international and the usa 2016 version look the same on the outside and are the same length yet some sources conflict. its hard to find a case for the usa 2016 version because the phone size changes with the case manufacturers. the 2015 cases should fit the usa version of the 2016? i couldn't get the incipio 2016 to fit my usa 2016 phone but i could get the tech21 eve tactical 2016, to fit. so cases are a try in person until more manufacturers confirm correct fit.
