just watched the video above and the only thing samsung done is improved their chip in comparison to their last year's exynos (which they should have done anyway as it is a new chip). however they still behind in the same areas as last year when compared to Snapdragon. I don't mind so much the difference in max performance but the main thing for me is the battery life and camera quality differences as shown in the video. Dont get why samsung do this 😒. I literally waited for s21 hoping it would be better, pretty disappointed.
