Korean here, people don’t like the countries itself, (we literally hate Japan), but doesn’t have much feelings to companies or usual people. (We buy Sony products, talk with Japanese people, study in Japan or work in Japan companies...etc)
Similar with China. It’s something different... and I’m pretty sure if there is a reason the 3 companies (but I’m not sure if Sony has a significant mindshare in the Android market... isn’t Japan’s phone market Apple + Samsung + < 10%?̊̈) make an Android-compatible OS, they would, and we also would use it.
The more I think about it the more feasible it actually seem. Sony doesn't have a market share that's proportional to their technology at the moment but they can actually occupy the high-end lines in this new ecosystem.
Japan, China, and Korea. Three countries that love eachother. /s
