Rumour has it that the design for the Apple iPhone 8 might just come with a form of facial recognition features, coupled with wireless charging.
Apple iPhone8 will introduce facial recognition generated from an infrared sensor on the front camera. It will be interesting to see how Apple will engineer this facial recognition for the iPhone, and lets hope they lessons have been learnt (or at least leveraged) from Samsung who introduced an iris scanner with less than robust results.
Apple typically believes it has no need to lead the next step change, it can follow what works for other handset manufacturers.
So what about the default in-the-box earphones? Rumours of their demise due to the AirPods are nonsense. The new iPhone 8 (and 9, 10,11,12...) will come with lightning port earphones for the LONG foreseeable future.
The reason for this is the economics of the product cycle.
It is important for Apple's business model to expand the iPhone's market reach to emerging markets who will shun the expensive (and very 'western') AirPods. As the iPhone becomes a more mature product with smaller step changes, it is crucial profits are maintained by selling more units in these relatively untapped markets.
So headphone, earphones, earbuds or whatever you call them are here to stay.
