Apple has developed new Face ID hardware that they are currently testing with a COVID-like landscape in mind, according to sources.
Internally, for testing purposes only, Apple has developed a prototype case that fits around iPhone 12 that they are using to test a new Face ID array.
The case fits snug around the phone, with a very visible extra sensor array sitting above the device. This prototype case allows the iPhone 12 to bypass the regular Face ID array, in favor of using the new hardware within the case.
By our measurements, the prototype array matches the same layout that we saw in the iPhone 13 CAD files that we made public back in June.
