The manufacturers promise us to use the hottest new technology and that exclusively. If that doesn’t sound like a damn big catch at the same time. 
The current ZTE Axon 20 5G confirms the assumption that the front camera behind the display panel has so far been anything but a good idea. Other manufacturers do without it for a reason.
And honestly, why did ZTE even take this step?
The people there must have realized how much this attempt backfires once this camera is actually used by the customers.
The well-known DXOMARK also ended up with a destructive test result; the front camera achieved the second worst value ever with 26 points.
Under-display front camera fails all along the line
The list of counterpoints is long, that of the pros is very, very short:
- Visible color casts and shades
- Unnatural skin tones
The re is a lot of noise in photos and videos- Limited dynamic range in photos and videos
- Artifacts such as hue shift, flare and color fringing in still images
- Common mistakes when estimating portrait depth
- Low level of detail in portrait mode
- Strong optical ghosting in videos
- Color shading and quantization in videos
- Ineffective stabilization, residual movement when standing
- Artifacts in video encoding in low light
That was good:
- Exposure generally stable for photos
- Focus is stable
In my opinion, this achievement cannot be glossed over with pioneering work.
