I was looking at a display note 10, and noticed it had built in screen recording. There was a whole button for it on the notification bar and everything. So, I was wondering about it coming to the older versions of the notes too? As well as the older galaxies.
The option is exclusive to the Note 10 to screen record using the quick settings menu, We are unable to speculate about the release of future updates. I recommend keeping your device updated so if the feature is returned, you will then have it!
Hope this finds you well!
