Hey guys, first time posting.

Proud new owner of a phantom 4, upgraded from a phantom 2 v2.

When I go into image transmission settings in the go app on my tablet it doesn't show me any signal values on any of the channels. In auto or custom.
All my firmware is up to date and the app is running version 2.7.1 I've noticed this since I purchased it. But it will show them on my phone when it's connected. Any ideas?

Have you updated your drone and rc to the latest firmware? In the screenshot it is an Android tablet, I'd suggest you to try other devices as below:
