But there is a punishment for those who try to allow a Snapchat to live on in the form of a screenshot. The sender of the disappearing message receives notification that a screenshot of the message was taken. This was done to allow someone sending an X-rated Snapchat message to know who is sending him/her those threatening blackmail letters.
Once iOS 7 is installed on Apple iPhone and Apple iPad units through the land, those days of knowing if that Snapchat picture of you wearing nothing but a smile has been memorialized using a screenshot. The release notes for iOS 7 beta 2 says that "Active touches are no longer canceled when the user takes a screenshot." Because the removal of an Active Touch is how Snapchat determines if a screenshot has been taken of a message, on iOS 7, Snapchat users will not be able to know if one was taken.
Can Snapchat come up with a fix that will allow message senders to know when their secret messages have been kept for posterity? If not, the release of iOS 7 could mean the beginning of the end of this innovative and quirky messaging app.
