Do take this particular rumor with a pinch of salt, as until there is an official statement released by the company itself, everything else will have to be looked at with a dose of skepticism. Even if it was a OnePlus live chat rep who allegedly reported such a date.
While we wait, we might as well have a refresher on what the OnePlus 3 will come with – first of all, there should be a 5.5” display that sports Full HD resolution, a speedy Snapdragon 820 chipset under the hood, 4GB of RAM and 32GB of internal memory or 6GB of RAM and 64GB of internal memory, a 16MP shooter at the back, NFC support, and a 3,500mAh battery.
