QR Code are pretty common, and until today I used a third-party app to scan the codes and get the embedded information such as a webpage. But I’ve just read in LinkedIn that the default camera app can read QR codes. No need to install any third-party app, no need to reach any menu, just point for two or three seconds and it will work as shown in the short video below.
I’m always running out of space on with Xiaomi Mi A2 phone since it only has 32GB flash, and no MicroSD card slot. So if beside saving some time while scanning QR code, I can get rid of one app that’s always a plus.
Except it does not work on my phone. Instead I had to tap on the right of the camera app to switch to Google Lens (or launch Google Lens manually), and the QR code will automatically be detected.
It’s not ideal. but it does save me a bit of time since I don’t need to look for the QR code app, and only a tiny bit of space since the QR code occupied only around 13MB on the phone. For reference, Google Lens takes around 37MB on my phone…
Reading LinkedIn comments seem to confirm direct scanning QR code does not work on all phones, but the camera app in iPhones, Samsung and Google phones should decode QR codes automatically by just pointing at them for 2 or 3 seconds.
