I've been able to control my Hero 5,7 &8 with my android tablet in landscape. I will check again but I think my phone works in landscape. I'll let you knowIf you can download the GoPro app to your Ride Command, then you can make it work.
Problem I've run into...just trying to control the camera from my Android phone...is that the app is "portrait" only. And I want to be able to use "landscape".
Have written to GoPro and mentioned it in a chat...seems useless to do so.
