Few days ago, I was taking a picture of a machine and the camera app showed a tooltip saying View details I tapped on it and a new screen appeared saying Product in the title and a list of numbers in it.
I have not managed to get that screen/tooltip again, but I am curious to know what it was, any idea? It is on a Honor 5C with Android 6.
Honor 5C Camera App used for scanning the QR code and obtain the contacts !! explains this as a smart way to add contacts without typing
Go to contacts
Click on the QR code of the contact
The QR code will be appearing on the screen
Open the Camera App in the Honor 5C phone
Click on the View details. Click on Create new contact and Click on Add to contacts
I don't have that device but this seems to be what you saw and introduced in EMUI 4.1
