I have a ‘18 Suburban Premiere. When i go to settings and turn display screen off, it comes back on in 30 seconds or less. Has anyone else experienced this?

If you are connected to the Bluetooth or to be sure via cable, I think it will turn on when you get notifications.
Try disconnecting all devices and no cables connected, or just try to use “Don’t disturb mode” on your smartphone
