This is somewhat late.
I went to a non-Samsung store and I already saw there the J7+ and J7 Core, all beside the J7 Pro.
Tbh, none of them were impressive. J7+ is a J7 Pro with secondary lens, but not really worth the extra Php4,000.00 price. J7 Core I think is more suited to gaming with a powerful and efficient Exynos 7874 (same as those on the J7 Pro and J7+) but comes with a more power friendly 720p display. I wish the battery was larger though, given its purpose as a mid range gaming smartphone.
[deleted post]Malaysia J7+ also runs on Mediatek P20, which is the main reason why i decide not to buy it, Hopefully Samsung realize that consumer expect either Snapdragon or Exynos for a phone at this price tag, or else we can always get a Huawei or Xiaomi with much better specs for the same price.
