Market research firm IDC has just released smartphone numbers for the first quarter of the year, focusing particularly in the Chinese market. The figures reveal two very interesting "first time" facts. For the first time, Apple has unseated Xiaomi, believed to be the forever king of the Chinese smartphone market. And also for the first time, that market is starting to show signs of contracting, if not decelerating, due to the saturation of the market. If it becomes a trend, it could very well change the way foreign brands look at the Chinese market.
