Whenever OnePlus announced a new phone, it feels like the company stands without competition in whichever price bracket it hits. However, with Xiaomi selling the Mi Mix 2 (review) in India this year, OnePlus has some real competition to deal with. When we compared the OnePlus 5 (review) to this phone, we found that the latter's camera prowess was equal in most cases, while Xiaomi did a better job at low light shots. In the OnePlus 5T (review), the company has improved low light imaging, by adding wider aperture camera sensors. That's an important distinction since the two phones otherwise match each other on most other aspects.
