The Google Pixel 2 and the Pixel XL 2 will be launched on October 5th. Evan Blass says in his tweet, that the 2nd gen Pixel phones will be powered by Qualcomm Snapdragon 836 processors.
The Pixel 2 is allegedly a 5-inch device from HTC, and the Pixel XL 2 is a 6-inch device from LG. What you see above, are leaked cases of the Pixel 2 The phones will allegedly skip the 3.5mm audio jack in favour of a USB Type-C port.
Qualcomm hasn't unveiled the chipset yet, and we can only assume that it plans to do so along the phone's launch. This is a bit surprising, considering that the chipmaker launched the Snapdragon 821 (last year's 2nd-gen processor) in June 2016, about 8 months after announcing the Snapdragon 821.
In comparison, the Snapdragon 835 was announced in January 2017, co-engineered by Samsung. And it appears that the Snapdragon 836 will be announced nearly 9 months after its predecessor.
Both the Pixel 2 and Pixel XL 2 can be expected to run on Android 8.0 Oreo, which was announced earlier this week. And we are not sure whether there will be a third phone which has been rumoured for a while.
