OnePlus, maker of the OnePlus One and OnePlus 2, has started on an incremental release of OxygenOS 2.1.0, the third OTA update for OnePlus 2.

Through a forum post, dated Sept. 21, OnePlus announced that it has begun to roll out OxygenOS 2.1.0 to a small percentage of OnePlus 2 owners. If the first wave of updates is successful, the manufacturer will proceed with a broader release aimed to reach more devices.

The released update is roughly 39 MB, but as far as mobile software updates go, this is quite an extensive one since it contains improvements that will influence user experience. It also contains fixes for various bugs found in OxygenOS 2.0 that got shipped with the handset and builds upon the previous improvements and fixes that came with OxygenOS 2.0.1 and OxygenOS 2.0.2.

The update adds manual mode to the camera to give users more control when snapping photos with the OnePlus 2. The update also includes support for the RAW image format for third-party apps that use it. However, OnePlus says RAW support is still not working properly for all apps after the patch. The Chinese manufacturer promises that it will investigate the problem, and users can a expect a follow-up regarding the issue.

The update also adds improvements to the display. Once the update is installed, users will get a new color balance slider that will enable them to adjust the display's color tones - cooler or warmer, depending on what pleases the eyes.

Some bugs that caused complications with third-party applications are now fixed. The lag experienced when turning on and shutting down the "airplane mode" is also removed.

OnePlus is yet to make comments on whether the coming patches will address the battery life and issues that came with the fingerprint sensor.

OnePlus 2, with its USB Type-C connector, is one of the highly sought after handsets today. A minute after it launched, all 64,000 units got sold and a million reservations were made.
