Knowing how to scan QR codes can simplify your life and broaden the scope of your interactions with devices and services.
Getting Started: Preparing Your Samsung Galaxy S21
Before diving into the scanning process, it’s essential to ensure that your Samsung Galaxy S21 is ready to read QR codes.

Camera Application: Your Primary Tool
The native camera app on your Samsung Galaxy S21 has a built-in QR code scanner. This means you won’t need to download any third-party applications to get started. However, it’s always good to familiarize yourself with the camera settings to ensure you’re ready for scanning.
Scanning QR Codes Using Your Samsung Galaxy S21
Scanning QR codes is a straightforward process on your Galaxy S21. Let’s break it down into clear steps.
Step 1: Open the Camera App
