For those that have followed the state of camera software in AOSP and Google Camera in general, it’s been quite clear that this portion of the experience has been a major stumbling block for Android. Third party camera applications are almost always worse for options and camera experience than first party ones. Manual controls effectively didn’t exist because the underlying camera API simply didn’t support any of this. Until recently, the official Android camera API has only supported three distinct modes. These modes were preview, still image capture, and video recording. Within these modes, capabilities were similarly limited. It wasn’t possible to do burst image capture in photo mode or take photos while in video mode. Manual controls were effectively nonexistent as well. Even something as simple as tap to focus wasn’t supported through Android’s camera API until ICS (4.0). In response to these issues, Android OEMs and silicon vendors filled the gap in capabilities with custom, undocumented camera APIs. While this opened up the ability to deliver much better camera experiences, these APIs were only usable in the OEM’s camera applications. If there were no manual controls, there was no way for users to get a camera application that had manual controls.
