Further analysis will determine the unique features of this sensor.
OmniVision, a long time supplier of sensors for iOS devices, makes the iSightHD (1.9-megapixel) front camera:
As noted by Chipworks, Apple’s ability to fit these sensors into an even thinner phone is likely due to the “thin touch screen with fewer layers, a thin battery, and the use of thin camera modules using the latest technology.”
