The Phone update from Dec 14 2017 broke the function of the screen waking up on an incoming call when the phone is connected to any Bluetooth device. When someone calls you, you can't see who's calling. This only happens when a Bluetooth device is connected. Happened on my Google Store bought Pixel 2, but also happened to my friends Pixel one. We are both on Verizon.
Go to the Play store and uninstall the Phone app. This will not disable the phone, but it will roll back the update and the screen will wake up correctly. Careful not to update the app until Google figures this out.
