First , in your camera Settings, Enable Scene Optimizer ...Second ,Do the same thing on your camera screen, i put a picture to show you where to Enable it on the camera screen...
You will find QR code in the Settings also, just Enable it too
This is the best way to scan a document and a code
by far the easiest to use and share. well worth the pro version. you can send a pdf, sign a document, cloud a document the list goes on.
