I also noticed that whenever you delete a comment, with the Liftoff app on Android you can open a menu of the deleted comment, click “Nerd stuff” and still read what the comment said. This means that the contents of the comment are never actually deleted. It’s simply tagged as deleted but the content is still there. I think you can currently only counteract that by editing your comment first, then removing it.
that’s interesting… wouldn’t that kind of sensor consume a lot of battery? turning the camera on and off every time you use it, and to determine the distance I assume it’s autofocus?
