Allow the phone app to remotely activate an available OTA update if they are not near the car and the car is in a safe mode for this.
The Tesla phone app gets a notification when an OTA update is ready. From the app, you can elect to install the update if the car is parked. Available in late 2018 with version 9.
(The comments saying otherwise are for older software that didn’t have the feature).

@moderator: I don't use android, but according @green1 comment, i'm not sure your can really initiate the update process only with your phone, with is the subject of the feature I suggest... If not, please remove (Implemented) status.
I feel like I'm missing something here ... the screen DOES show there's an update available, as a clock icon next to the T in the middle of the top bar on the screen. Touch it and you can start the update any time ...
