Looking for an open source, trustworthy (in terms of knowing exactly what it does and what it’s capable of) QR scanner, then check out ‘Privacy Friendly QR-Scanner App’.
It’s quite sad of the amount of downloads for QR/bar code scanners on the Google Play store filled with ads, trackers and potentially malicious background activates, some of them are downloaded in the millions.
Some people though know that it does not have to be that way. You can download it via their website or via their F-Droid page (if you want to know more about F-Droid, you can read it here) or even Google Play.
