All of you weirdos out there will love this...
The great thing about Snapchat has always been that you can send a picture or video for 0-60 seconds and then it goes away forever (as long as it isn't replayed). That is now changing with on of the new features in Apple's new iOS 11.
iOS 11 now offers a "screen recording" feature that allows you to take a video screenshot of whatever is on your phone and saves it to your Camera Roll.
So in case you are one of those people who send embarrasing, ugly or even naked pictures and videos, you better watch out!!
