OxygenOS 3.2.2 update for the OnePlus 3 contains other improvements like added NFC toggle in quick settings, enhanced noise cancellation in video recording, and an updated 4K video recording codec, as per the changelog on the OnePlus forum. The update also addresses the alert slider/silent mode issue and contains the latest security patches and various optimisations.
OnePlus 3 has also received an official support for CyanogenMod 13, and nightly builds are now available for users to flash on their phones. However, as pointed out by Android Beat, there are a couple of issues with the build in its present form. As OnePlus has not given out a binary release, Dash charge is currently not supported by the build.
Also, the post-processing applied by the stock camera app on OxygenOS is missing in the CyanogenMod 13 build and as a result, the pictures taken by the camera take a major quality hit. However, an official CyanogenMod release indicates that the build is reaching a stable point and is expected to sort out minor bugs soon.OnePlus and Cyanogen parted ways in April last year as Cyanogen had a different goal than OnePlus' on the software front, which resulted in the breaking up of the deal, Cyanogen's Founder CTO Steve Kondik explained later.
