For years, Google's Nexus devices have been synonymous with stock Android. While they may be showcases for new features, they still represent the baseline for what the platform can do. That might not last for much longer, though. CEO Sundar Pichai told guests at the Code Conference that Google will "thoughtfully add more features" to Android on Nexus phones going forward. The company will also be more "opinionated" about the design, the exec said. Third-party companies will still make the hardware, but it's evident that rumors of Google taking greater control of the Nexus program were well-founded.
