June this year SM-G610 (Samsung Galaxy On7 2016) was spoted and now we can see second variant with Exynos 7870.
And here you have both versions:
System: Android 6.0.1.;
SoC: Snapdragon 625 (SM-G610)/Exynos 7870 (SM-G610F);
RAM: 3GB;
When paired with first On7 (2015) it’s big step in power (Exynos 3 Quad + 1,5GB RAM).
Hope to see more info about this model in short time.
