To make quality photos you must have a phone that has the manual camera option, then you will find a lot of options there. To take pictures at night you must have ISO as little as possible and exposure time as long as possible. In these pictures I used iso 50 and 10 second exposure time, that means for 10 seconds the phone is not allowed to move at all. Do not try to take pictures from your hand because you will make blurry photos, just take the phone if you do not have a tripod and set it somewhere to stand. You will take more pictures because you often see almost nothing but just after the picture is ready. It's not easy at night to make pictures but the results can be amazing.
Pictures taken with Samsung Galaxy S7 EDGE iso 50, 10s exposure time by me:)
