How to scan a QR code on Samsung Galaxy Tab A?

[Android Central Question]

I am running Android version 8.1 and Samsung Internet 9.2.10.15. Previously, we had Samsung Internet 5.2.30.25, and I knew when to enable the QR code scanning in that version (under Extensions), but I can't find it on the new version.

I also tried downloading an older version of Samsung Internet from APK mirror, but it said "Application not installed." But it is...

I'd like to use the built-in QR code scanning of the existing apps, rather than installing a dedicated app. Is that possible on the versions I mentioned above?

The application you were tying to install didn't install because there was already an app of the same name installed. (Only updates can install over installed apps.)

Try Barcode Scanner.
