OnePlus releases OxygenOS

Oxygen OS, One Plus' flavor of  Android, was expected back on February 12, but has faced a number of delays as the build was going through a certification process. Now the company behind the OnePlus One is finally ready to unveil Oxygen OS to its users.

Oxygen OS is Based on Android 5.0.2 Lollipop,and is said to be “light and essential” with all the customization, and useful features OnePlus owners have enjoyed with their devices. Gestures are baked in, and quick settings have some nice appointments. There is also a welcome File Manager built into the platform.

As you can see from the feature video above, and as anticipated, OxygenOS is really a feature augmentation to Lollipop, as the experience looks almost completely stock. That no doubt lends to what looks like smooth and fast performance on the hardware.

OxygenOS is an optional download for OnePlus One users, who  can still opt to keep using Cyanogen ROMs. OnePlus is committed to be prompt with updates, and encourages users to download the company’s feedback app to submit comments about the experience.
