Phones with Cover and inner selfie cameras

On a foldable, the cover screen is the display used while the phone is closed. Taking a selfie from it means using the rear camera rather than the front one — and the rear camera always has a better sensor and lens than the front.

This value says the phone carries a separate selfie camera on the cover side and another on the inner screen when opened: a quick frame while closed, a video call while open. They are separate hardware and their resolutions may differ.

So this is the foldable body's real dividend on the selfie side: you frame on the outer screen and photograph yourself with the phone's best camera.
