Bullish on the multi-billion dollar opportunity in the Indian smartphone segment, OnePlus said it expects India to become its biggest market in the next few months.
OnePlus announced its foray into India with the launch of its 'One' smartphone at Rs 21,999.
Users in India will receive India-specific invites through OnePlus and Amazon.in. The two platforms have been integrated so that invites can be used to purchase the device exclusively on eCommerce major, Amazon.in.
OnePlus One sports a 2.5GHz Qualcomm Snapdragon 801 processor, 5.5-inch display, 3GB RAM, 64GB memory, 13MP rear and 5MP front camera, 3,100 mAh battery, 4G support and NFC.
It runs CyanogenMod 11S, a custom aftermarket version of Android, developed by Cyanogen.
OnePlus is developing its own version of Android Lollipop-based OS (the latest version), which will be released for Indian users next month. A final build of the OS will be released in February next year.
The company has partnered with HCL Care to offer after- sales service across 20 cities in India.
