Thankfully, there's a QR code reader built into all Google Pixels, but you wouldn't know it unless you stumbled across the feature. Really, it comes down to this: the most annoying thing about QR codes is not their functionality, it's the amount of time it takes to scan them.
Why is my Google pixel not scanning QR codes?
To sum up, if your Android device won't scan QR codes, go to Camera Settings, and enable the QR code scanner option. Additionally, press and hold the QR code screen area or the Google Lens button. If the issue persists, download a QR code scanner from the Play Store.
Why QR code is not getting scanned?
If a QR code won't scan, it could be because the QR code error correction level is too low for the amount of damage the QR code has sustained. Or it could be that the QR code error correction level is so high—and the original code itself so complex—that the load times are inordinately long.
