No, it’s just a good to have. I have made this art-piece as a demonstration (it’s a link to this post):
And here’s me reading it without a problem:
You said that „QR Codes won’t work without the white margin.”. I said that they don’t even need all of the code to work, and that they don’t need margins.
Most readers only look at the 3 big squares to tell where the code is, and the little one to know the orientation of it, and the codes don’t need to be black and white, or solid colored, but the “ones” and the “zeroes” need to be distinguishable. Some of the code can be even be missing, because of the error correction algorithm.
I support this idea, and based on the things I read here, it seems to me that different cultures have different norms for asking a question, and that’s a good thing, but can create not so pleasant social situations here in the internet
I have no problem with questions on forums, sometimes I ask them myself, but I think that if you expect people to try to answer your question, people should be able to expect you to have tried looking for an answer yourself.
This type of answer wouldn’t exist if people typed the question into google instead of reddit/lemmy/forums/etc…
Try building from the revanced manager, it should allow you to login. Also, install microg.
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.
Here’s a pretty good qr-reader I can recommend: https://play.google.com/store/apps/details?id=com.blogspot.aeioulabs.barcode
