Google Pixel features 24/7 live customer care service built right into the phone. This allows you to easily contact Google support for the phone either by phone or by chat and the support team is available to help you out all day in every day of the week.
You can use the customer care app to also search the help articles, which you might find an answer to your problem there and there is also an access to tips and tricks that will help you make the most out of your brand new Google Pixel phone.
Another great feature makes it easier to help customer support agents to solve your issues with the phone by enabling the screen-sharing option, which allows customer support not just hear about the problem from you but also seeing everything happening on the screen. This will help the agent solve the problem quicker and in a more efficient way.
When you contact the support agent, the agent will ask you if you want to share your screen and will send you a "View screens share request", which you need to accept in order to start sharing a live feed of your screen with him.
I think it's an amazing feature that really shows that Google really wants you to enjoy the device and want to provide you with a professional assistance so you can focus on enjoying the device, rather being frustrated with issues which you can't solve yourself.
As you can see from the video above, the user can follow the agent instructions as he instructs him what to do using ripples on the screen that show the specific place he needs to interact with (e.g. pushing a button, choosing an option from a list of options). The agent has no way to control your phone and you can always pause or end the screen sharing session.
