ZTE’s technical achievement of getting a functional camera under an OLED screen involves new types of transparent materials, pixel filters, and demosaicing algorithms to make sense of the light that hits the 32-megapixel sensor. But the result, unfortunately, is a bad selfie camera. ZTE's Axon 20 5G has come out of hiding and it’s worth looking at: 
 

• The selfie photos are pretty bad. 
• It may be a world first, but it comes in a distant second to the quality of selfies you’d expect from a today’s phones.
• The phone looks pretty solid

(Take note: the module is less visible in real-life — here we can see it through the camera due to the Moiré effect of the pattern. David says it looks much better in person: “ZTE tries to hide this area by using default wallpapers that are dark near the top. In practice, this works very well. When viewing the phone with darker colors near the top of the screen, you probably won’t notice the camera at all. if you’re using a white background, it’s a bit more obvious.”)
