The OnePlus team today released a “daily-driver-material” build of OxygenOS 3.0 — based on Android 6.0.1 Marshmallow — for the OnePlus 2 for community testing before it prepares the rollout of the final OTA.  To ensure that the final build is relatively bug free, the team wants its community to test the build for any network, performance and battery life issues. OxygenOS 3.0 also comes with some major improvements to the camera app and performance and the team behind the OS is looking for feedback on it. If you install this version of OxygenOS 3.0 on your OnePlus 2, you will receive future OxygenOS OTA updates, so you don’t have to worry about flashing back to an older version of OxygenOS to get the final Marshmallow OTA update on your handset. A mini change-log of the update is below:
