Open Camera app
To scan a QR code using the built-in camera app on your Android device, follow these steps:
1. Locate the Camera app: On most Android devices, the Camera app is pre-installed and can be found in the app drawer. Look for an icon that resembles a camera or the word "Camera."
2. Open the Camera app: Tap on the Camera app icon to open the camera. Make sure that the rear camera is active, as that's the one used for scanning QR codes.
3. Align the QR code within the viewfinder: Position your Android device so that the QR code is visible within the viewfinder of the camera app. Make sure that the QR code is fully visible and in focus.
4. Wait for the notification banner: Once the camera app recognizes the QR code, a notification banner will appear at the top of the screen. This banner will contain information about the QR code, such as a link or text.
Once the notification banner appears, you can tap on it to view the information or take the appropriate action. For example, if the QR code contains a link, tapping on the banner will open the link in your default web browser.
Align QR code in viewfinder
To ensure successful scanning of a QR code using your Android device's camera app, it's crucial to properly align the QR code within the viewfinder. Here's how you can do it:
1. Ensure proper lighting: Make sure you're in a well-lit environment to provide sufficient light for the camera to capture the QR code clearly.
2. Steady your hand: Hold your Android device steady to prevent blurry or shaky images. If possible, use a tripod or place your device on a stable surface to minimize movement.
3. Position the QR code: Place the QR code within the viewfinder of the camera app. Make sure that the entire QR code is visible and not cut off by the edges of the viewfinder.
4. Adjust the distance: If the QR code is too close or too far from the camera, the camera may have difficulty focusing on it. Adjust the distance between your device and the QR code until it appears sharp and clear in the viewfinder.
Once you've properly aligned the QR code within the viewfinder, the camera app should automatically detect and scan the code. If the QR code is recognized, a notification banner will appear at the top of the screen, allowing you to view the information or take the appropriate action.
Tap notification banner
Once the QR code is successfully scanned by your Android device's camera app, a notification banner will appear at the top of the screen. This banner contains information about the QR code, such as a link, text, or contact details.
To view the information or take the appropriate action, simply tap on the notification banner. Here's what happens when you tap the banner:
1. Link: If the QR code contains a link to a website or online content, tapping the banner will open the link in your default web browser.
2. Text: If the QR code contains text information, such as a message or a set of instructions, tapping the banner will display the text on your screen.
3. Contact details: If the QR code contains contact information, such as a name, phone number, or email address, tapping the banner will open your device's contact app and allow you to save the information as a new contact.
In some cases, the notification banner may also provide additional options or actions. For example, if the QR code contains a link to a downloadable file, the banner may give you the option to download and save the file to your device.
View or take action
After tapping on the notification banner that appears when you scan a QR code on your Android device, you will be presented with various options to view the information or take the appropriate action. Here are some common actions you can take:
- Open link: If the QR code contains a link to a website or online content, tapping on the notification banner will open the link in your default web browser. You can then view the website or content directly.
- View text: If the QR code contains text information, such as a message or a set of instructions, tapping on the banner will display the text on your screen. You can read the text and take appropriate action if necessary.
- Add contact: If the QR code contains contact information, such as a name, phone number, or email address, tapping on the banner will open your device's contact app and allow you to save the information as a new contact. This makes it easy to add new contacts to your address book.
- Download file: In some cases, the QR code may contain a link to a downloadable file, such as a document, image, or video. When you tap on the notification banner, you will be given the option to download and save the file to your device.
These are just a few examples of the actions you can take after scanning a QR code. The specific actions available will depend on the type of information encoded in the QR code.
