For good low light camera smartphone you are better of with the Sony XA1 (f2.0 apperture but with relatively big sensor at 1/2.3") or maybe any of the current Samsung J5 or J7 series with the f1.7 apperture lens or even the Oppo F5 at f1.8 for main camera but not sure about the sensor size. On my research recently I found out that most of the cheap mid range dual camera smartphone kinda fall apart in low light high ISO situation. Especially the Nova 2i and the Honor 7X. Basically you would want the lowest f number you can have paired with the biggest sensor you can find for example a 1/2.3" sensor. Your reference would be the Flagship of Samsung the Note 8 which has a f1.7 and 1/2.5" sensor size. Cheers.....
