I recommend using a dedicated qr scanner instead of google lens, because even if it can scan qr codes, it isn’t optimised for it. Sometimes it can’t even detect a medium-sized qr code in a screenshot, and it looks like they haven’t even implemented the full standard.
Not open source, which is a red flag for me. There are QR scanner&generator apps on F-Droid, and you can check the source code that they do NOT send the scan result to some server and do NOT sneakily take a pic of you with the front camera.
In cases when privacy isn’t important (here, Google can match my Google and Lemmy usernames, and I leave a public comment), you can use Google Lens (in browser!) and crop the area of focus, and unlike most QR readers that only apply a linear transform (perspective correction), it works for QR codes on bent surfaces.
