This is the end of leaps and bounds of innovation in the smartphone sector. Everything will be minor incremental innovations and a gradual saturation of the hardware capabilities of devices. I can't think of any sensors not already on phones. I can't think of any innovation in hardware, apart from the usual pace of improvement in speed, computing power and efficiency. I don't think phones will be getting any bigger. There is a point of screen pixel density beyond which it is impossible for the human eye to differentiate quality. Maybe there will spring up a market for innovative attachments to phones. Maybe phones will become portable computing powerhouses for bigger machines.
