Starting from the iPhone X, Apple introduced Face ID, when it did not choose off-screen fingerprint technology, more or considered that the technology is not mature enough. However, during the epidemic period, many users are troubled by the inconvenience of taking off masks for facial recognition in public places, and I believe apple has also noticed the emergence of this situation.

All along, the iPhone has been using Face ID as its only biometric function, according to the supply chain news, Apple is optimizing the new iPhone product line, hoping that through cooperation with Samsung, Qualcomm and other international companies, it is expected to add fingerprint recognition functions under the next generation of iPhones, breaking the embarrassment of Face ID caused by the epidemic.
Some industry insiders bluntly said that the cost of fingerprint recognition under the screen is low, and the size is small, the supply chain is more mature, if Apple wants to re-import, there will not be too much problem in terms of yield and design.
In addition, the production capacity of fingerprint recognition chips under the screen is also higher than in the past, and the risk of chain breaking is low. Upgrading from touch ID in the past to under-screen fingerprint recognition can also become a new selling point for Apple, which is worth looking forward to.
