It's raining Chinese smartphone brands in India this monsoon as OnePlus prepares to follow Xiaomi into the country with its smartphone OnePlus One.

Initially the Chinese company is offering the One smartphone on an invitation-only basis in India according to its blog post.

Recently China's Xiaomi tasted success in India with the first launch phase of the Mi 3 and this seems to have prompted other big Chinese smartphone brands into considering the big Indian market.

Coming to what OnePlus One smartphone is all about, here's what you get:

Beginning with features, OP One sports a big 5.5-inch LTPS IPS display with 1080?1920 pixel resolution offering a pixel density of 401ppi. The display also boasts of Gorilla Glass 3 protection and the same adaptive backlight technology that's seen in some Sharp displays.

The device has the distinction of being among the few to have 3GB of RAM. OP One is powered by the quad-core Qualcomm Snapdragon 801 clocked at 2.5GHz with Adreno 330 GPU.

It sports a 13-megapixel rear IMX214 sensor with a six-lens array and f/2.0 aperture that offers quick shutter speed of only 0.3-seconds. There's also a 5-megapixel front-facing camera. The phone does not have a microSD card slot, so you have to make do with the 16 or 64 GB onboard storage.

OnePlus One phone comes with a customised version of CyanogenMod ROM called CM 11S. The software is based on Android 4.4 KitKat. Connectivity is 4G LTE (region dependent) and you get Wi-Fi 802.11 a/b/g/n/ac, Bluetooth 4.0, and NFC functionality. There's a 3100mAh non-removable battery too.

In other countries OnePlus One (OP One) is available at a starting price of $299 (unlocked and without contract) for the 16GB model (about Rs 18,000), and the 64GB variant is priced at $349 (around Rs 21,500). But remember, right now the OnePlus One is only available through an invite system.
