I agree that the front camera logic is broken. In theory the "Front camera" setting in Settings should only function to enable or disable the front camera display when setting it to "D" and NOT affect the manual activation of the front camera just like the Plaid mode setting is coded where it just enables or disables the Plaid animation upon accelerating.
One other suggestion that I thought was pretty nice on this T8 8.8 inch display that I was also looking at is that they have a function where if you do a one firm swipe down on the right scroll wheel to swap between camera and normal display UI. Also they have a function where you can swap between carplay/AA and the normal display UI with one light press of the right scroll wheel.
Would it be possible to send that feedback to the folks you interact with to forward it to the manufacturer for incorporation? It would be nice if they can incorporate both these features onto this F9 display since I find those 2 features convenient unless there is a shortcut to both these features already that I am not aware about.
At the 29:05 and 29:16 mark where you can toggle between camera and original UI with one click on the right scroll wheel firm swipe down on the right scroll wheel. At the 29:18 mark you can see the toggle between original UI and carplay/AA with one press of the right scroll wheel.
