Yes, but by using their own chips in a big market they're making their users leave for iPhone or potentially other android makers that don't ruin your battery life like Exynos. Typing this from a hot S20 plus 😔
Will wait to see how it plays out. Seems that the Exynos 2400 is expected to be less crap then the past few gens of Exynos processors, so so long as it's not going to crater battery life or performance vs the Snapdragon models I'm not fussed.
