What about Touch ID under the display? In the middle of a pandemic, where it is more and more difficult to unlock the phone wearing masks, I won't understand Apple not implementing it on the 2021 lineup. I understand that they didn't implement it on the iPhone 12 lineup because the design of an iPhone takes years. But hell, even on the Side button, like the iPad Air 4!
I was seriously thinking on getting this year's iPhone mini, but if we have to rely only on FaceID to unlock the iPhone, I am waiting yet another year. And nope, I don't have an Apple Watch.
