App information QR code

I have been wondering for a long while… What does this QR code do? I think that is for Z18 users but it seems to be useless to other users like me…

This is an old feature from Ratio. If you access a non-system app (any app you downloaded from the Play Store basically), it will link to the Play Store page for that page.
We’ll probably be refining this menu in the future so its a bit more useful, perhaps allowing you to share an app directly with your contacts
