QR Code Scanner is an Android app made for scanning QR codes and barcodes with a phone camera. Its main job is simple: point the camera at a code and let the app read the information.
The app can be used for many everyday tasks. It can scan product barcodes, coupons, contact details, phone numbers, emails, calendar events, and Wi-Fi information.
After scanning a code, the app can suggest actions based on what it finds. For example, a phone number can be used for a call, while a Wi-Fi code can be used to add a network. The app also keeps a history of scanned codes.
Space and Security Info
A reliable current MB download size is not available in the public app information used for this review, so I will not give a made-up number. The actual installed size and cache can be checked on an Android phone under Settings > Apps > QR Code Scanner > Storage.
The app’s main scanning job uses the phone camera. Basic code recognition can be done from the camera, but some actions after scanning may require internet access, depending on the type of information in the code.
The available app description says the scanner is free to download and use. It also says there are no hidden fees or in-app purchases.
Because this app works with a camera, users should check the current Android permission screen before using it. Camera access is needed for live scanning, and users should review any other permission shown by their phone before allowing it.
Real Device Test Run
A proper two-day Redmi test should include QR codes from screens, paper, product packaging, and different distances. It should also check how quickly the camera opens, how fast codes are detected, and whether the result screen responds without delay.
The test should record battery percentage before and after scanning sessions. It should also check phone temperature, camera lag, crashes, scrolling, and any visual problems.
I cannot honestly say that I completed this physical two-day Redmi test. There are no measured Redmi results for battery loss, heating, frame drops, or crashes available here, so I have not created numbers and presented them as real test results.
The available app description says the scanner can read codes in seconds and is designed with a simple interface. That is a description of the app, not a replacement for a measured phone test.
Best Features to Use
- QR Code Scanning: The app can read QR codes using the phone camera. This is useful when you need to open or read information stored inside a QR code.
- Barcode Scanning: It also supports barcodes. This can help when checking product information or other barcode-based content.
- Action Suggestions: After reading a code, the app can suggest actions based on the result. Examples include calling a phone number, saving a contact, sending an email, or adding a calendar event.
- Scan History: The app keeps a history of scanned codes. This can help users find information from an earlier scan without scanning the same code again.
- Wi-Fi and Contact Codes: The scanner can recognize codes containing Wi-Fi or contact information. This gives users a quick way to work with information stored in those codes.
Alternative Apps
QR Code Scanner competes with Google Lens and dedicated QR scanner apps built into some Android phones. Google Lens offers QR scanning along with image search and other camera tools, while a dedicated scanner can be quicker for users who only want code scanning. This app focuses mainly on QR and barcode scanning and keeps a history of previous scans.
