Until now, we haven't seen any other smartphone brands release their devices with an under-display camera besides ZTE. As we've come across many reports saying that the technology is difficult to be perfected due to the balance between display and light transmission, that might be the reason why others are hesitant to release one. The good news is, OPPO has scheduled an event on 4 August to unveil its second-gen under-display camera technology, and we might see something that persuades others to give the technology a try.

If you were aware, ZTE is currently working on a 2nd-gen under-display camera on the upcoming Axon 30 series. According to sources, it seems that the company has already released a teaser hinting of its arrival this month.

When we talk about the under-screen camera, we must not forget that ZTE is the first smartphone maker to bring the technology into the market with the Axon 20. After making such a brave move, the company is reportedly working on the next-gen under-screen camera.
