This is a camera review.
The pictures taken using the main camera looks great, as long as the lighting is good. When it comes to lowlight pictures, they are very grainy. The pictures taken using telephoto camera are most of the time soft / out of focus. It does look like you can take good pictures, but you have to be very lucky.
When it comes to video recording, it doesn't get any better. Recording in 4K 30fps with the main camera, it looks grainy, even outside on a sunny day and worse in lowlight. The focus on the telephoto camera is better, when compared to the photos that I took. It does however look more grainy than the main camera.
I was very surprised about the night vision camera. The pictures looks great, even when zooming in. But I would recommend to take al least two pictures of the same object. This is the first smartphone that I have seen, where the night vision camera can record in 4K. You have to walk slow for better image stabilization and I would not recommend using the 2x zoom. I was recording in complete darkness, so the 30fps dropped down to 10.64fps.
