I know there are many features that make phones good or bad, but also i’m a dual sim big user and that’s something I take into account when buying a phone, and that’s why I love my A7 2017 phone, now I see A8+(succesor of my device) and it doesn’t look much much better than my A7, I think i’ll pass on this A8+
Exynos 7885 has a dual core A73 cluster, which is much faster than the Exyno 7880’s A53 cores. Multi core performance will be somewhat similar, but 7885 is massively faster in single core performance, which matters more.
