I bring this question up because with the recent Note 7 discontinuation/recalls I'm afraid that Apple will just give us the same play it safe boring design for 2017 and scrap any idea of a complete redesign. OEM's may start holding back features to prevent a repeat of the Note 7 disaster.
Should we be worried that 2017 will lack smartphone innovation?
The S8 will be out early next year before the next iphone and Apples engineers will have already have designed most if not all of the next iphone so i doubt that they will stop and switch their attention to a gentle rehash of the 7. Extensive product testing and manufacturing takes up 6 months of the year. I am pretty sure that the next gen phone is already in build and design phase
