Note that there are many different kinds of black screen issues. Please respond only for those matching this description: Upon getting into the car, the screen is black for about 25 seconds followed by the T for a second or two and then the normal screern. Lte connection takes a further few minutes. By "no apps," i mean anyting that might keep the car awake such as TeslaFi. I have done a lot of searching and have found quite a few samples but also a lot of "not for me" and no resolutions. In my trials last night and early this morning it appeared to happen ever other time. I wait 10 or more minutes between tries. I then did a break press, two button full system reboot and now it has been happening every time.
