The OnePlus 3T has also a good camera. If you need some more lowlight performance out of your phone, I can recommend the Samsung Galaxy S7 or the S8.
If you want to try the newer dual-lens options, you got Huawei P9 or P10 (1 monochrome sensor, 1 normal sensor), the LG G6 (1 normal lens, 1 wide-angle lens), or OnePlus 5 (1 normal lens, 1 "telephoto" lens with 2x optical zoom).
That's all I can think of right now, I hope it helps you decide. Cheers!
