OnePlus 3 gets OxygenOS 3.5.1 Community Build: What's new and how to install

Step-by-step guide to install OxygenOS 3.5.1 update on OnePlus 3.

OnePlus has released the OxygenOS 3.5.1 Community Build with numerous bug fixes for the OnePlus 3 just a week after the flagship phone received the OxygenOS 3.5 update. Although this is an incremental release, it brings a plethora of improvements over the previous build.

According to the official release, the new update returns Dark Mode functionality while Android Pay and system UI tuner are still inoperative. Besides, avid OnePlus fans should note that if they dirty flash (flashing ROM without wiping) from previous build of OxygenOS to 3.5.1, they could lose the home screen setup.

On the brighter side, this update (aka Community Build 2) brings bug fixes for audio issues unearthed in the previous build.

Here's is the complete list of features ported into the OxygenOS 3.5.1 release as reported on the official OnePlus Forums thread:

  • Accent color added
  • Battery icon customization added
  • LED customization added
  • Display sRGB added
  • Night mode added
  • Dark mode theme optimized
  • General bug fixes

Interested OnePlus 3 users who are running the stock OxygenOS can go ahead and download the new update here. Alternatively, those who have already installed the OxygenOS 3.5.0 update can check for the new update via Software > Settings menu.

Key Points to Remember

  • Back up all your important personal data on the phone including photos, videos, and user files, before you proceed.
  • Ensure OxygenOS 3.5 Community Build is installed on your OnePlus 3 and the device must be running the stock Oxygen Recovery.
  • Verify that TWRP recovery is installed on the phone and the device is not rooted.
  • The OxygenOS 3.5.1 firmware has not been tested with handsets running on Custom ROMs or custom recovery software. If you try to overwrite on custom software, you will risk potentially bricking your device.
  • If you flash this Community Build, you will only receive community over-the-air (OTA) updates and not official OTAs. You will need to manually clean install official builds to continue receiving official OTAs.
