If you have contact Snapchat with a person that you like to keep a photograph that sends you through the application, then there is a possibility that you can do using a screenshot, although doing so will be notified to the other person you took a snapshot, which can create a conflict if they disagree with it.
Take a screenshot in Snapchat is simple as it is done the same way as any other application. However, unlike other, Snapchat notifies the user when another has taken a screenshot of a photograph, so it is important to consider this.
Screenshot from iOS : iOS users must press simultaneously and for a couple of seconds and keys on startup. Instantly mobile informed that the catch was taken.
Screenshot from Android: Not any mobile operating system supports this screen by default, but there are two possible combinations for devices with Android. The first is the same as the IOS, ie simultaneously pressing a couple of seconds during the ignition and starting key. Meanwhile, the second option is the same as pressing keys on and volume.
For those who want to take Snapchat capture without the other person noticing, there are several additional applications requesting some data from our own but who are able to make screenshots without notification to be sent to another user.
