If you believe insiders, then no update on biometric sensors in the new iPhone 13 should be expected. Of course, Face ID will be smaller, but no Touch ID will appear in the button or under the display.
But this does not mean that we will never see new sensors. The company’s patent has appeared on the network. It describes the placement of Face ID under the display to identify the owner by face and Touch ID, respectively, by fingerprint.
The patent refers to “translucent holes” in the display and “invisible gaps in the material.” The most important thing that Apple cannot accept is optical distortion. If, during testing, sub-screen sensors affect the picture or affect security, then they will be abandoned.
And the last thing that is said in the application is the thickness of the display modules. They can get thicker, but no bangs.
