ZTE Axon 30 5G UDC might be well-hidden but still disappointing

The smartphone market has been trying to push for full-screen displays for a long time now, but no single solution seems to stick around for long. From cutouts to popup cameras, every year sees a new design or mechanism designed to minimize the amount of screen real estate taken up by the front camera. Ideally, the solution would be an under-display camera or UDC that's completely hidden from view. In practice, even ZTE's upcoming Axon 30 5G shows how we're still a long way from that ideal.
