I doubt this issue can be solved in one product iteration. But I'm sure will be solve eventually in a hand-waving 1-2 years don't-challenge-me estimate.
I am also skeptical people want the phone given how tablets sales lowered as bigger display tablets reduced as phones got so big it bled tablet demand from below and chromebooks bled tablets from above.
My choice of the word skeptical does not mean I think it will fail, means I am open minded and need to see better evidence. I do personally often carry a phone and a tablet, but some of those reasons is 2 devices in case 1 fails and their combined battery power. e.g. a 8" tablet to watch on a flight and I can let its battery run down, then I switch to a phone for Uber etc then switch back to tablet for bedtime TV, etc. The current cost of a phone+tablet, very capable, is <$1000. So one device $2000 doing both, is challenging to understand.
