There has been a lot of scanders on screen or sensors under the screen, most of which are designed to remove bevels or even a screen cuts. The first to go was the fingerprint scanner, now followed by the camera in front of the front. Apple has long abandoned the first, preferring to keep a wide notch to feed its replacement of the face ID to fingerprint sensors. However, the company has not renounced the contact ID completely, however, its next evolution may not appear on the iPhone 13 later this year, after all.
When Apple eliminated the contact ID of the face of your telephones, the Android convention of relocating the fingerprint sensor on the back or side followed. Apple did not follow the tendency to use scanning scanners on the screen, but, instead, stuck with the identification of the face through thick or thin. Apparently, that is not your final game, but that touchdown ID is far from coming soon.
According to Bloomberg Mark Gurman, Apple has been testing an on-screen version of ID Touple for quite some time. While it is intended for a future iPhone model, it will not be making the cut this year, apparently. In fact, the sources of the supply chain indicate that there is no difficult time line for technology.
However, the scenarios for ID touch screen implementations are quite curious. One possibility is that iPhone Pro models use on-screen face ID, while base models will change to touch screen ID. Another option would be for models that are not pro continue using notches while the Premium line goes with face ID under the screen.
Both scenarios, of course, require Apple to adopt face-screen ID, as well as on-screen screen ID. It has been proven that the first is quite difficult to get the right, and it is unlikely that Apple will put a solution that is not satisfied with production.
