No need for third party app to scan QR codes on Android

Almost every Android phone these days comes with the Google app, and you don't need anything more to scan a QR code. The application has a built-in scanning tool called Lens. It helps you identify objects, landmarks, text, and numbers you see in the real world, but it's also capable of processing QR and bar codes. Some phones, however, come with integrated QR code scanners. For example, you can enable scanning in Samsung's camera settings or use Bixby Vision.
