For anyone finding the qr reader unselectable for the lock screen buttons, don't forget to first enable it in the quick settings tile.

To anyone that didn't know Android has a proper built-in qr reader (camera app UX isn't very good for qr), same here. Just learning that and finally uninstalling 3rd party was probably the most important feature of this update...

Wait, doesn't Pixel camera app support QR code? I agree that its not ideal app to read a code, but it's better to have by default. It's the same feature as iPhone, so beginner user will find (or taught by iPhone user) it works

Isn't is ubiquitously available via Lens? By default, it's right there on the home screen.

Assuming someone actually knows it (most non-engineers will likely install an app not finding one called QR), I find the UX to show a small, non-persistent link hover on top of the code difficult to use compared to a normal qr reader (both built-in or 3rd party) which freezes with a large clickable region when it detects a code. Especially when outside and lighting conditions or angles can make scanning a code a challenge, having to actually click to complete a scan would always be a big problem for me, so eventually I installed a third party app. Finding the built-in "app" was nice to allow uninstalling that.

This may be a more important issue in Japan where I think? QR codes are more used than in the US and often require scanning around other people, or other physical challenges. I guess most here get around the problem by using an iPhone though which has a built in and highly obvious QR app.
