I wonder what it really includes.
Apparently, it also includes the S21's QR Code Scanner App - "Instead of simply opening the camera app when you tap the QR Scanner toggle in the notification shade, you now get a dedicated QR scanner app that was first introduced on the Galaxy S21 series. In addition to scanning QR codes with the camera, you can open QR codes saved in the device gallery, a functionality that was also added to the Galaxy S21 lineup with a recent update." - Quote from SamMobile article! Not that, that's a big deal, but it adds real estate to the patch, for sure!
