The Android 5.1 update for Cyanogen OS, which brings it to version 12.1, is now rolling out via an over-the-air update to OnePlus One devices starting today. Not only this but the OTA update will also begin to rollout for other Cyanogen devices in the next few days.

What’s new in Cyanogen OS 12.1?

There’s a new LiveDisplay feature that adjusts the screen based on environmental and sensor data to also Cyanogen’s own browser that they are pitching as the fastest browser on a smartphone. In addition, the 600MB update brings the usual security and bug fixes to keep the OnePlus up to date with the latest security vulnerabilities found in Android.


The OTA update should be hitting devices soon, but if you can’t wait then you can go ahead and download Cyanogen OS 12.1 below and flash the ZIP file manually.

  1. Thanks foie the article. I have a Oneplus One from those that doesn’t come with the Cyanogenmod logo on the back. Can also apply this Rom?

  2. This update ruined a really good experience I had with this phone… The dialer for example is useless now and since it needs rooting to change it, I’ll say goodbye to Cyanogen as soon as I find sure time for flashing
