I'm looking at purchasing the p4p from a friend and it's got the controller with a screen but i want to use my tablet for the camera view.  Does anyone have experience doing it like that?
Thanks.

Hi there. Thank you for reaching out. If you want to use your own tablet as a monitor for the DJI Phantom 4 Pro, you may need to purchase a separate controller without the built-in screen and connect it to the DJI Phantom 4 Pro aircraft. Hope this helps. Thank you for your support!

The controller with built-in screen doesn't work with an external screen. If you need to use the tablet, then it's a standard controller that you'll need.
