I was kind of annoyed that there wasn't an icon in the notification pull down bar for starting a mobile hotspot so I created a shortcut on my homescreen and started it up so I could make sure it was working properly to my tablet. The weird thing was after I did so, bang! the hotspot icon magically appeared in my notification pull down right beside the Cast icon! I'm not complaining, I wanted that, but anyone else notice this? That's the 2nd undocumented part of this phone I've discovered in 2 days
