OnePlus 2 users are in for some good news as OnePlus has just started rolling out the latest Oxygen OS firmware with build number 2.1.2, which brings a bunch of bug-fixes and performance improvements to the flagship smartphone. Although the same update version 2.1.2 is being rolled out for both OnePlus 2 and OnePlus X, the feature changes seem to be quite different.

The OnePlus 2 gets an improved preview interface for the camera with various performance improvements and fixes for RAW format on third-party camera apps. Users of FV-5 camera app will be receiving a new update from the app maker to support RAW on OnePlus 2 devices, soon after the device gets the new Oxygen OS 2.1.2 OTA update.

The FV-5 camera update carrying the build number 2.79.5 will likely hit your device, just a few days after upgrading to Oxygen OS 2.1.2. The complete list of fixes and improvements ported into this update are listed below:

  • Improved UX for preview in Camera
  • Performance improvements on app install and launch
  • Individual icon customization support
  • Fixes for RAW format on 3rd party camera apps
  • Russian & Turkish language support
  • Lockscreen wallpaper support
  • Security patches
  • Bug fixes to System Update to improve OTA stability
  • General bug fixes and performance improvements

Those who missed the OTA update notification or cannot install it for some reason may try installing the same manually, using the step-by-step guide provided below.

How to install Oxygen OS 2.1.2 OTA update on OnePlus 2

Method 1: For non-rooted users with stock recovery

Step-1: Copy the downloaded update file to the root folder on the phone and remember the location. Alternatively, you can download the file directly to your phone.

Step-2: Reboot the phone into recovery mode

  • Turn off the phone and wait for a few seconds until the screen shuts down completely
  • Press and hold the Power and Volume buttons together until some text appears on the screen
  • Using the Volume button, scroll down to the recovery mode option
  • Hit the Power button to select it and your phone will now boot into recovery mode

Step-3: In recovery mode, use the Volume button to browse and locate 'install update' option and hit Power button to select it

Step-4: Go to the folder where you have saved the downloaded Oxygen OS 2.1.2 file, select it and confirm installation

Note: If the OTA file fails to install using this method, you may try flashing the 2.1.1 full ROM (using method 2 below) before retrying the OTA installation. This should fix any problems.

Step-5: Once you confirm the action, the update should start installing automatically

Step-6: Wait until the installation completes and then select Reboot system now to restart the phone

Your OnePlus 2 should now be running the latest Oxygen OS 2.1.2.
