To say the iPhone X raised some eyebrows with its biometric authentication system would be an understatement. Apple dropped the Touch ID-enabled home button for its design and introduced Face ID as a replacement. This form of device unlocking relies on advanced image processing to recognize an owner's face and keep a phone secure. However, it restricts the unlocking options open to anyone who uses an iPhone X and has been known to fail besides.
Some rumors have alleged that Apple will address these issues by re-introducing fingerprint scanning for post-iPhone X phones. However, the classic home button will not be coming back with it. According to those leaks, Apple may have patented a form of in-display fingerprint scanner, much like that of the Oppo Find X.
However, even more recent leaks suggest that this is not the direction Apple will take with its new patents after all. They suggest that the company is developing a different type of novel sensor instead. It will be based on multiple components under a dielectric layer that build up a 3D image of the fingerprint for the purposes of device unlocking.
Presuming this rumor is true, this measure may be intended to compete with the purported Galaxy S10 and its own rumored in-display reader. Furthermore, even if such a patent by Apple really exists, there are no guarantees that it will feature on the iPhone X's immediate successor.
