How to Scan a QR Code With an LG Phone
LG Android smartphones are capable of scanning two-dimensional barcodes called Quick Response codes. While phones like the Ally, Optimus or Revolution don't come preloaded with the necessary program to scan QR code, you can download one in a few easy steps. Numerous scanner applications are available in the Android Market, and many are free of charge. You'll then be able to use your phone's camera to scan codes, and the application will decode the information the code contains.
Install a Scanner Application
Touch the "Applications" launcher icon on your home screen to open your full menu. Touch the "Market" icon. The Android Market will open.
Touch the magnifying glass icon, located in the upper right corner of the screen. A search box will open. Type "barcode scanner" into the search box. A list of available applications will display just below the search box, arranged in order of popularity.
Touch an application from the list to read more details and reviews. When you are ready to download, touch "Download."
Review the application permissions, then touch "Accept and Download." Installation will begin. Touch the "Home" button to return to the home screen while your scanner application installs in the background.
Using the Application
