While it appears that such is the case for Instagram Direct, Snapchat will still let you know when someone is screen recording your privately messaged snaps. Thanks to a tipster who emailed us this morning, we decided to test out sending both still images and videos through the two previously mentioned apps, and discovered that Snapchat treats iOS 11's screen recording feature just as it does for taking a screenshot.
If your iPhone is locked, you'll get a push notification saying someone "took a screenshot!" of either your photo or video, and if you're within the app then Snapchat will still display the double-crossed arrows and let you know that the receiver took a "screenshot just now." So, while Snapchat isn't able to directly tell you that it's a screen recording on iOS 11, you'll still know that your DMs are being saved. Stories, on the other hand, appear to be less abiding to the screen recording/screenshot notification system, at least for now.
Instagram Direct doesn't yet appear to have such a feature for iOS 11 screen recording warnings. Similar to Snapchat, Instagram Direct lets you send disappearing photos and videos to other users, and includes a screenshot notification whenever the recipient captures the content you sent privately.
In tests on iOS 11, neither photos nor videos captured via screen recording in Instagram Direct told the sender that such an action had taken place. If screen recording becomes a bigger issue for these private messaging apps, and others like them, it's likely that developers will begin to implement more direct warning systems for users to look out for.
