Details of the upcoming Honor 20's cameras have been revealed. The phones, the Honor 20 and Honor 20 Pro, are said to feature camera hardware similar to the Huawei P20 Pro and the new P30 Pro. The big, RYYB and RGB sensors are also joined by telephoto and ultra-wide angle lenses.

P30P smears largely like the P20P, with interpolation artifacts and a serious loss of color resolution, I don't think a smaller sensor with a higher pixel count is going to perform better.
