Snapchat is one application to post temporary messages. Messages are temporarily available after they have an expiration date. But it seems that Snapchat programmers added an extra feature to the conversations.
The new feature allows you to delete a message that has been sent on Snapchat. It works in one-on-one messages, but also in group messages conversations. 
Let's see how you can delete a message sent to Snapcaht.
First, you'll first need to update Snapchat to the latest available version. The feature works only in the update. This means that if your friends are using an older version of the app, you may not be able to delete a message you have sent to an interpersonal chat.
After updating the app, you can test the feature by sending a message to a contact you know has the latest version of the app. Long press the message you just sent and a menu will appear. You will see that there is one choice "Deletion."
For the new feature to work, several conditions must be met. In initial tests, you may not see the Delete button, or when you first delete a message the app will tell you that it will try to remove on the part of your friends. However, he may not do it. The reason; A bad internet connection, or an older version of Snapchat from your friends.
When you delete a message in Snapcchat, it will appear in screen You've deleted a conversation. ' However your friend will not see the same message.
The best way to make sure your message has been deleted is to do so as soon as possible after sending it. If your friend has not seen the message, you should delete it before it appears in the conversation.
With Snapcchat group conversations, you can delete your message even if it has been seen by half.
