Thanks you mentioned quality of recorded audio. If you could add shutter speed of frames in video, would be best. Is it 1/24sec since it takes 24per sec? Even 24 would be enough if it was recorded for example with 1/60sec or beter speed.
Snapdragon 810 killed the interest for 90% of the Android flagship. For now generation flagships I would only consider Samsung with Exynos 7420.
