A lot of selfies from the 32-megapixel under-display camera look like this: hazy and just not good. Even budget phones like the Nord N10 5G have better selfie cameras. I'll let some comparisons do the talking.
See? I told you they were bad. Image quality is hazy, soft, and in low-light, terrible — absolutely potato quality. The $300 Nord N10 5G, $350 Pixel 4a, and $400 iPhone SE 2020 all take better selfies and cost less than the more expensive $450 ZTE Axon 20 5G.
Other than for bragging rights — ZTE being able to claim "world's first" — I’m honestly not sure. Rushing to market makes even less sense since ZTE just announced a second-gen version of the in-display camera with twice the pixel density (400 ppi vs. 200 ppi on the Axon 20 5G.
ZTE really should have waited before releasing this half-baked tech. Time will tell if in-display cameras have legs like in-display fingerprint readers or will fade into obscurity like so many phone gimmicks.
