However, interestingly enough, that feature might not debut on the iPhone first, but could instead find its way to the iPad. This is according to Twitter user L0vetodream who has recently posted a treasure trove of leaked Apple product information, one of which claims that an in-display Touch ID sensor could find its way to future iPads.
We say that this is interesting because in the past, new hardware features typically find their way to iPhones first before getting ported to the iPad. However, in recent years, the iPads have been getting the newer features first before the iPhone, like the 2020 iPad Pro that comes with a LiDAR scanner.
It is unclear which iPad model will receive this rumored in-display Touch ID sensor, but last we heard, Apple was said to be working on a high-end iPad Pro with a mini LED display, so perhaps that could be the model to receive said feature.
