Capturing low-light scenes with the LG G5 and the Galaxy S7 edge is a hassle-free task on both phones. They are well equipped with OIS and wide apertures to handle low-light scenery, and you can't go wrong with either of them.
Still, the LG G5 has the advantage when capturing still images - it has a higher resolution sensor, with wider FoV. Throughout the scenes we shot, the G5 bettered the Galaxy S7 edge almost every time, even though not by much.
Switching to 4K video recording, the LG G5 once again edged the Galaxy S7 edge (forgive us the pun!), which makes it the overall winner in this shootout.
The Galaxy S7 edge has a significant advantage over the LG G5 at 1080p recording, capturing amazing videos unmatched by the G5 and it also offers a wider field of view in this mode. It often outed better colors than the G5 and is a lot more capable when shooting indoors where the light is really low.
So with the 1080p videos and the indoor shot aside, the LG G5 consistently won over the Galaxy S7 edge, so if we are to pick a winner for this low-light shootout - it has got to be the G5, though not by a large margin. Once again, though, both phones are very well equipped to handle any low-light situation you may decide to shoot, so you won't be disappointed by either of them.
