The Pixel 2 and Pixel 2 XL have experienced one of the sloppiest Google phone launch ever. It all started with display issues with the Pixel 2XL. Those issues were followed by the PIxel 2 speakers making popping noises. The Pixel 2 and Pixel 2 XL is now experiencing random reboots for some users. This apparently happens when the phones have a difficult time handling low-signal LTE. Not even a factory reset will fix this issue and you may need to contact Google for a return if you are experiencing this issue.
