I've only owned my 3 for a few days, but to this point whenever I get in the screen has been on immediately. Tonight I came out to the car, opened the door via phone key, and...nothing. Lights and all that were on, but the screen wouldn't come on. I tapped around on it a few times, tried shifting into drive / reverse. Maybe 10 seconds later, the "T" appeared on the screen as if the car had been rebooted and then all was fine. I hadn't explicitly turned the car off on parking, I had just put it in park, and got out. I even "woke up" the car via app about 5 minutes before I went out to it. Is this something I just don't understand or did it do something weird?
