The most disruptive option I could think of? Jettison the entire concept of creating yet another closed ecosystem on a specific device brought out by a specific manufacturer. Instead, create a hardware-agnostic OS, capable of running on top of any piece of mobile hardware. Don't even bother trying to license it to manufacturers; instead, sell it directly to the public, as an option to increase features or maintain support for mobile devices that the original manufacturer no longer provides adequate support for.
