Early last year, known Apple analyst Ming-Chi Kuo predicted that the company would be transitioning to an in-display Face ID system. This would mean that future iPhones would finally be able to offer a notchless display. Now, rumors indicate that this could indeed happen with the iPhone 15 Pro in 2023.
@LeaksApplePro tweeted recently that Apple is no longer working on an under-display fingerprint sensor. The iPhone 14 Pro (?), which is apparently now being trialed by Foxconn, is speculated to fully ditch any form of Touch ID and instead offer improved Face ID in a punch hole instead of a full notch.
If that is indeed true, it is very well possible that the iPhone 15 series in 2023 will abandon the notch altogether. Apple is expected to adjust its development efforts in improving Face ID and opt for an in-display camera technology that alleviates the need for a notch.
On the Android side of the fence, under-display cameras in phones such as the Xiaomi Mi Mix 4 and the ZTE Axon 20 haven't really performed on par with conventional implementations. Apple had reportedly planned to introduce an under-screen camera in the iPhone 13 Pro but refrained from doing so given that the technology hasn't fully matured yet.
With the iPhone 14 Pro reportedly getting a smaller notch, it can be presumed that the iPhone 15 Pro will get rid of the bezels and the notch for good. How well that camera would perform is something we will have to wait till at least next September to find out.
