reinstall the app unless you mean "Vision" included with Bing
I use this one, of course it now costs $1.99 where I got it free 7 months ago.
If it's low light this one also has a hard time scanning at times. Vision I never use
Yeah, I have this issue with my 1020, that said it has a terrible focusing distance....I hope they allow you to have manual focus in the future - you mean the QR scanner built into WP right?
many people met with such a problem about camera not focus so that can not read barcodes,you may check this thread named:Camera does not autofocus in barcode scanner ,hope you can find the solution ! Good Luck! https://forums.motorola.com/posts/7843725a7f
