What smartphone feature would you actually be excited for a company to implement?

I want the future phone improve the quality of the real calling.
The connection and the real value of itself are getting down.
People focus on the applications but not calling quality.

I'd be very excited to see smartphones being built with true two-way radio communications, mesh network capabilities and the ability to use more outdated but proven forms of communication.
There are a few companies building accessories that can add this functionality but I'd like to see it built in from the factory. I'd also like to see solar charging, wireless charging and other forms of charging be built-in as well.
