Odd thing is the proximity sensor is already under the screen, this is suggesting it is being brought to the surface and integrated into the dynamic island. Less expensive 940nm laser and sensor though by doing so.
Someone needs to tell IQE's share price! I don't see why the face id sensor cannot be also be used as a proximity sensor. Anyway, just speculating. All we have right now.
This is intriguing....... scope for utilisation of the previously abandoned 940nm material? Does not align with the timelines that have been guided though. Then again, we all know about company guidance.
