No.
There will always be masses of people who don't give that much of a crap about their pictures, just as long as they take good enough shots to recognize friends/family/pets, vacation sunsets, and food. These people aren't going to pay full-frame prices for a camera, nor will they deal with the hassle of shlepping a big camera around because their phone cameras are good enough for their purposes.
And there will always be people who may want to get more serious with their photography but can't afford the upgrade or aren't serious enough to be bothered with full-frame.
Now, if you can put full-frame into a phone and seriously drop the price, then who knows. Until then, nope.
