FTFY

is it always running, looking for barcodes in all the photos you take?

Has Google’s camera app added that yet? If not it’s only a matter of time.

When my phone’s barcode reader app sees a web link, it fetches the page’s title to display next to the actual link. So it is going to that web server and fetching resources by itself. Even though it isn’t actually rendering the page and running javascript, it might be exploitable.

Half of them will print the highest bandwidth regardless of the actual cable’s capabilities so that won’t help.
