Gurman: Apple testing iPhone Duo 2 prototypes with Face ID

Mark Gurman reports that Apple is already testing iPhone Duo 2 prototypes with Face ID, with the sensor integrated under the outer display. Touch ID on the first iPhone Duo was one of reviewers' biggest complaints. The feature isn't guaranteed for next year's model and could slip to a later generation.

• iPhone Duo 2 prototypes include under-display Face ID on the outer screen
• Face ID reportedly didn't fit in the first iPhone Duo's thin chassis
• Apple is shrinking Face ID, with under-display IR camera expected on iPhone 18 Pro
• Face ID may not ship in Duo 2 and could arrive with iPhone Duo 3
