After a long delay, the OnePlus One smartphone finally receives its version of Android 5.0 Lollipop. Cyanogen announced on its official blog site that OnePlus One owners can now have the latest Cyanogen OS 12, or the company's version of the Android operating system. 

"Our Lollipop ('L') update begins to roll out to all OnePlus One device owners today. Enjoy sweet additions and improvements in our latest software release, above and beyond the goodness in Android Lollipop. YU Yureka device owners will be treated to the Lollipop update coming very soon," the official announcement said. 

Cyanogen OS 12 reportedly comes with all the new features of the Android 5.0 Lollipop, including the material design elements of the software featuring interaction design, visual and motion design, as well as graphic animation. 

Cyanogen also features a new email app powered by Boxer for the first time. The email app comes with a number of account support, email exchange support, as well as template responses that can be used for faster replies. The other customized features for the new email app includes sound alerts like bells or whistles, and a selection of different LED color display that can be used for email notifications, among others. 

The International Business Times released the steps on how to install the Cyanogen OS 12 operating system on OnePlus One smartphones over the air. Users just need to follow these steps: 

For OnePlus One owners: Select "Yes, I'm in" when a notification is received. When download is completed, select "Install now." The smartphone will restart automatically and its operating system will be updated to the new version. 

For manual download: Users should go to the device's "Settings" then go to the "About phone" tab, select "System update" and "Check Now." 

The system update came months later than expected after the mobile operating system suffered several delays.
