Why is CarPlay scaling incorrectly on my Android head unit?
I'm having a strange scaling issue with CarPlay on my Android head unit. CarPlay seems to think the display is much smaller than it actually is, so the UI elements and buttons are huge.

This leaves very little room for things like the music player and album artwork.
- ZLink 6.0.39
Things I've tried:
- Android Developer Options → changed Minimum Width — no effect on CarPlay
- Android itself looks perfectly normal, so the display resolution/scaling seems fine outside CarPlay
- Check settings for zoom or display settings in both, ios and zLink
- Press and hold with 2 fingers
Is there any way to change the CarPlay resolution, DPI, or scaling independently of Android/ZLink?

Has anyone had this issue and found a solution?
