Interesting to see how even hardcore android supporters found lags and unresponsiveness on the S7 :
we still managed to find lag across
the user interface, including random stutters and framedrops. Indeed, our go-to GPU profiling test showed many skipped frames when scrolling through the Play Store, significantly more than our 810 devices running stock or close-to-stock software (Nexus 6P, OnePlus 2). We’ve also encountered random input lockups where performance did not take a hit but we simply couldn’t interact with the UI for a few seconds (repeated instances on the camera app and settings menu, reported by two XDA editors).
