Comparison

The Huawei P20 Pro has a massive 40-megapixel main camera, which downsamples its output to 10 megapixels, thus giving you great detail and a manageable file size. It also has a second 8-megapixel sensor with a telephoto lens and a third monochrome sensor on the rear for improving the details in captured shots.

The Galaxy S9+ has a 12-megapixel main camera with the widest f/1.5 aperture, along with a second 12-megapixel telephoto camera. To know more details about each of these phones' cameras, be sure to check out our full reviews using the links above.

For the tests that follow, we disabled any and all extraneous features which might affect photo quality. This includes beatification modes for the front and rear cameras. On the P20 Pro, we turned off the Master AI feature which tends to artificially boost colours. We’ve kept most of the tests the same as in our previous comparison, so without further ado, let's dive straight in.

OnePlus 6 vs Huawei P20 Pro vs Samsung Galaxy S9+: Daylight landscape

In our outdoor test, the OnePlus 6 captured excellent details on a building, as well as the plants and trees to the sides of the frame. There was slight noise in the shadow regions of the palm trees, which was visible once we zoomed in, but overall, the photo was very good. However, the colour tone of all three photos was vastly different.the OnePlus 5(Review), Chinese smartphone maker OnePlus has been heavily promoting its camera chops to help it stand out from the competition. The OnePlus 5 was the company’s first phone to have dual cameras, followed shortly by the OnePlus 5T(Reviews), which actually ditched the secondary telephoto sensor for one that focussed on low-light performance. In our review of the OnePlus 5 and the OnePlus 5T, we found that the the cameras didn't quite live up to the company's claims, and that there was still lots of room to improve.

In this shootout, we’ll be comparing the cameras of the OnePlus 6 (Review) to that of more expensive flagships like the Huawei P20 Pro (Review) and the Samsung Galaxy S9+(Review). The reason we chose the P20 Pro is obvious - we've found it to be one of the best phone cameras out there, and it's also currently DXOMark's highest rated smartphone. We’ve also chosen the Galaxy S9+ since it was the best overall performer in our last comparison, in which we pitted it against the iPhone X (Review) and the Google Pixel 2 XL(Review).

The OnePlus 6 features a 16-megapixel Sony IMX 519 primary sensor, with a f/1.7 aperture, optical image stabilisation, and larger pixels compared to those on the 5T's sensor. The secondary rear camera and the selfie camera are exactly the same as those of the OnePlus 5T.
