A few weeks ago we found out that there was an issue with some third part cases blocking the Nexus 6P sensors in the camera hump. When case manufacturers build cases based on build schematics they are normally dead on, but when you buy cases early you still run the risk of something not fitting right or something being off. When you buy an official case from the company building the phone you purchased you expect everything to be perfect.
Android Police is reporting that the official case from Google is making it difficult to take screenshots with the Nexus 6P. The reason is that the case cover the power and volume rockers with a plastic button overlay. When the volume down is pressed during a screenshot the cover presses the volume up button as well. You can't take a screenshot if both volume buttons are depressed. When this occurs a bug report screen is launched instead of a screenshot being taken. Some users where so annoyed they took a knife to the case to remove the button cover. To resolve this you could use any case with an open button layout.
