How about comparison with smartphone at night ?

[TomG]

I was curious how a119s compare with very good camera im my Note 4 at night.

Not scentific, for fun. Two different devices.
I believe software in note4 not optimized for night video, and no information was put to codec. Gain should be applied before compression, so post processing gain is useless but it shows there no useful information in dark areas in Note4 file.

I have owned Galaxy S2, S4, and S6 and was always disappointed with low light performance in the real world. In reviews the Samsung flagship has always performed fantastically. In my hands, not so much.
