OnePlus One's CyanogenMod 11S OS revealed in leaked images
Engadget today received two screenshots of the OnePlus One’s OS (see above), thus confirming that this is based on Android 4.4.2 KitKat. The image on the left shows the lock screen, which displays weather information, messages, and battery status, among other things. The screen looks fresh and quite elegant. Unfortunately, that’s all that we can see from CyanogenMod 11S at the moment.
The OnePlus One will be officially revealed on April 23. It will come with a 5.5-inch 1080p display, a 13MP rear camera from Sony, a quad-core Qualcomm Snapdragon 801 processor, and a 3,100 mAh battery (with some special technology to make it last longer).
