OnePlus has posted a teaser on Twitter, which hints that a Snapdragon 821 device will be unveiled on November 15th.
The tweet says T-7 (T minus 7 days), for the launch countdown for the new device. But it could also be a subtle hint that the device is the OnePlus 3T.
So far the only thing we know is that the OnePlus 3T will be powered by a Qualcomm Snapdragon 821 processor, which was confirmed earlier by the chipset manufacturer. But OnePlus took to Twitter to drop another teaser, by announcing the clock rate of the SoC, which is 2.35GHz. The Snapdragon 821's (64-bit quad-core) Kryo CPU offers a 10% performance increase over the Snapdragon 820 processor, and a 5% performance bump improvement over the 820's GPU (even though they use the same Adreno 530).
A previous leak from Evan Blass, hinted that the OnePlus 3T could cost $80 more than the OneOlus 3, which puts it at $480 (about Rs. 32,000).
