OnePlus is doing a great job of getting out updates and bug fixes for their devices! The next version of OxygenOS, v2.1.2, is already rolling out for the OnePlus 2 and OnePlus X via OTA udpates. This update brings a few new features including a new camera preview interface, faster app installs, icon customization support, fixes to RAW capture, and more for the OnePlus 2. The update for the OnePlus X brings color offset fixes for HDR mode, low battery system optimizations, and all sorts of other bug fixes.
This update will not fix the issues that users are experiencing with SD storage, but OnePlus has stated they are aware of the issues and are working towards fixing them. The update is rolling out incrementally.
