Instagram is consistently copying Snapchat features, but now it has introduced a new feature for the privacy of its users. If some will take temporary snapshot of your direct message, this will be notified you. However, this feature of Instagram is rolled out with new update, and will work with messages sent or written later on.

With this feature users can do recording with device and other mobile phone but the idea of taking snapshots will be discouraged. Currently, this feature is only for iOS users.

However, we cannot say anything about Android availability and placement to other users.
