This is according to Mark Gurman at Bloomberg who claims that Apple is testing out an in-display Touch ID sensor for the iPhone 13 which is expected to be released this year. Whether or not this will actually make the cut remains to be seen, so there is still a chance that it might not debut with 2021’s iPhone.
However, Touch ID is expected to exist alongside Face ID, which will give users more options when it comes to biometric security on their iPhones, and having more options isn’t necessarily a bad thing. The report also claims that Apple’s approach to the iPhone 13 is that they are treating it more like an “S” model, meaning that there will be no major outward changes.
This means that the iPhone 13 will pretty much look like a copy of the iPhone 12, and that any changes Apple will be making will mostly be under the hood. The iPhone 13 is expected to be announced this September as Apple will be returning to its September/October scheduling.
