All the examples camera are not working

[wootu]

when i open the demo scene in my phone Iphone 7 IOS 10 and even on android its not turning on my camera its showing a white background the whole time. Is it a bug ? because from what i read on the description it suppose turn on the camera display.

And I'm trying to add my own gif animation / vid / obj to the vuforia demo but i cant seems to find where should I upload my content to. Cant seems to search where is the argon 3d text located or function to call it out. Could I have some help on this too? thanks :D
