The update — Cyanogen 12 — begins rolling out for “all” OnePlus One users beginning today, with other devices to follow in the future.
YU Yureka device owners will be treated to the Lollipop update coming very soon.
Cyanogen 12 brings Android 5.0 to the devices along with the full Material Design language across the tweaked OS. It also brings a new App Themer feature that allows you to change the style system-wide, including in third-party apps.
This new build of Cyanogen also includes the company’s new email service provided as part of a partnership with Boxer.
The only catch with today’s update is it doesn’t include the tweaks found in Google’s recently released version of Android 5.1, but those are landing soon.
