The much awaited Oxygen OS for OnePlus One is launched on 3 April, 2015. Oxygen OS is based on the Android Lollipop. OnePlus had issues with Cyanogen and Micromax in Indian Market, so they have decided to come up with their own operating system. The basic feature of the OS is it is simple, light weight and fast without any bloat wares.
To get a basic idea of other features this ROM have you can watch the video below
Gestures which allows you to open application by gestures like double tap to wake the device, draw ’V’ to toggle flash light etc. These gestures works even the screen is off.
Quick settings – The new quick settings allows you to access the settings which you use commonly easily. The icons can be arranged easily as per your convenience.
Customization – you can easily control the phone with hardware or software navigations keys, the lock screen is customizable.
OnePlus also developed a feedback application which you may or may not install. This application helps OnePlus to get your comments and feedbacks on the new OS and optimize it accordingly.
If you have already unlocked the boot loader and have TWRP is is easy to have the Oxygen OS. Otherwise you will have to unlock the bootloader and flash TWRP.
unlocking bootloader will wipe all the files from your phone (it is NOT like a factory reset). It will remove backups, photos etc. So make sure you move all the anted files from phone to some other devices.
