I think I will stick with S24U if the next flagship is with Exinos. I stick with Samsung because their software offers me everything I need because it comprises lots of office features.
Exinos is a deal breaker for me, Exinos phones are basically very good because they feature lots of features, but the problem is they are lagging (slow), they heat or overheat easily and the battery lasts alot less than Snapdragon.
For less heavy users though, I think Exynos chipset is OK, but for heavy users it's a no no, Snapdragon all the way.
