OnePlus 3T to launch on 15 November
OnePlus 3T is said to be an upgraded version of current OnePlus 3 OnePlus

Chinese smartphone maker OnePlus posted a video clip on Twitter teasing the launch of a new device powered by Qualcomm's Snapdragon 821 processor clocked at 2.35GHz. This is the same processor that powers Google's premium Pixel handsets.

The company announced via a tweet that it will be holding a product launch event at 1 pm EST on 15 November.

The tweet mentions the name T-7, which could be a countdown to the 15 November event.

November 15 might see the launch of the rumored OnePlus 3T, an upgraded model of current OnePlus 3, that has been in the news for a while now.

Even Qualcomm recently tweeted saying a new OnePlus handset using its Snapdragon 821 processor on the way, although it did not reveal details about device.

So what's new about OnePlus 3T? The upcoming handset is rumoured to pack Sony's new IMX398 camera sensor of 16 megapixel. It is expected to sport LCD screen instead of AMOLED. The Snapdragon processor might feature a 6GB RAM. Other expected key elements of the handsets are fingerprint sensor on the front, a front-facing camera of 8 megapixel, and a 3000mAh battery.

The handset is likely to ship with Android Nougat on board. Renowned Twitter leakstar Evan Blass AKA @evleaks earlier noted the phone would cost $479 (£385), which is $80 more than the OnePlus 3.
