To do this it needs your phone- number: on Android, this is obtained automatically. On iOS, however, you need to verify your number by sending a SMS to Snapchat with a unique code (partly to prevent abuse, but mainly because unlike Android, iOS does not allow system access to the device’s phone number). The Snapchat app makes a web service call to discover whether this SMS verification has succeeded or not.

Upon clicking on one, the video player will happily play the non-obscured video file just as if it were any plain old video. Simply put, an Android app should NEVER save data to the root of the user's sd card” Source: Gizmodo Dec 2012
