We are going to lose those abilities (except QR codes). WPCentral covered that in the article "Bing Vision lost all features but QR scanning
To bring back that "eye" icon from Bing search, install app "Tile For Bing Vision
" and pin an "eye" tile to your homescreen.
Alternatively, I have installed app named just "QR
", so I can start scanning from Cortana by saying "Open QR", or alternatively longer "QR scan QR code" (this works better in case you have installed multiple QR apps).
Also, app named "QR Scanner RS
" (or "QR Scanner+
") is good, that one can handle also EAN codes (barcodes), unfortunately it does not have speech support (Cortana integration).
