The OnePlus team has released OxygenOS for its OnePlus One smartphone. Based on the Android 5.0.2 Lollipop, the OxygenOS is developed by giving prime importance to performance and battery life over gimmicks and bloated features and at the same time, it keeps most of the original features in the OxygenOS, such as double-tap to wake, music controls, and shortcuts for the camera and flashlight.
According to the developer, “the main goal for OxygenOS is to provide faster, more meaningful updates and a better-integrated range of services for every OnePlus user”. However, the main decision following the release of OxygenOS may be due to the controversy with CyanogenMod licensing in India.
OxygenOS is based on the ASOP (Android Open Source Project) and this version of the custom ROM is built on the Android 5.0.2 Lollipop. It is free from bloatware apps, and has near stock interface. In this guide, we show you how to install OxygenOS on OnePlus One.
