You do not need a second phone to scan a QR code that is already displayed or saved on your Android phone. If someone sends you a QR code through email, WhatsApp, a website, or another app, you can save or screenshot it and scan the image directly.
The easiest method is usually Google Lens inside Google Photos. Samsung Galaxy phones can also recognize QR codes directly from images saved in the Gallery app.
Quick Answer
To scan a QR code from a screenshot on Android, open the screenshot in Google Photos, select Google Lens, and wait for the QR code to be detected. Tap the detected link or action after checking that it looks safe. On many Samsung Galaxy phones, open the screenshot in Gallery and press and hold the QR code until the detected action appears.
How to Scan a QR Code From a Screenshot With Google Photos
This method works on many Android phones, including Google Pixel, Samsung Galaxy, Motorola, OnePlus, and other devices that have Google Photos available.
- Open Google Photos.
- Find the screenshot or saved image containing the QR code.
- Open the image.
- Tap Google Lens. Depending on your version of Google Photos, you may need to tap More first and then select Google Lens.
- Wait a moment while Lens analyzes the image.
- When the QR code is recognized, review the detected link or action.
- Tap it if you trust the destination.
Google documents Google Lens as a way to get information from photos already stored on an Android device. See Google's official Google Photos and Lens guide.
You do not need to point your phone's camera at another screen when the QR code is already saved as an image.
How to Scan a QR Code From a Screenshot on Samsung Galaxy
Recent Samsung Galaxy phones can recognize a QR code directly from an image stored in Samsung Gallery.
- Save the QR code image or take a screenshot.
- Open the Gallery app.
- Select the screenshot containing the QR code.
- Press and hold directly on the QR code.
- Wait for the QR code notification or action to appear.
- Review the destination before opening it.
Samsung currently recommends this method for QR codes received by email, text message, another app, or displayed on the Galaxy phone itself. You can see Samsung's official Galaxy QR code scanning guide.
If press-and-hold does not work on your particular Galaxy model, use the Google Photos and Google Lens method above instead.
How to Screenshot a QR Code First
If the QR code is currently displayed inside an app or website but has not been saved to your phone, take a screenshot first.
On most Android phones:
- Display the full QR code on the screen.
- Press the Power and Volume Down buttons at the same time.
- Open the screenshot in Google Photos or your phone's Gallery app.
- Use Google Lens or your Galaxy Gallery QR detection feature.
Make sure the screenshot includes the complete QR code. Avoid cropping off the edges before trying to scan it.
What If You Don't See Google Lens?
If the Google Lens option is missing, first make sure Google Photos and your Google apps are updated.
Open Google Play Store, search for Google Photos, and install an available update.
If Play Store downloads themselves are stuck or remain on Pending, follow our Google Play Store not downloading apps guide.
You can also open the Google app and look for the Lens camera icon beside the search bar. Lens can analyze photos already stored on your phone.
QR Code in Screenshot Not Scanning? Try These Fixes
If Google Lens or Samsung Gallery cannot recognize the QR code, the problem is often the image itself.
1. Make sure the entire QR code is visible
The complete square should be inside the screenshot. A partially hidden or cropped code may not scan.
2. Use the original image if possible
A heavily compressed screenshot or image sent through some messaging apps can become too blurry for reliable recognition.
3. Crop out unnecessary parts of the screenshot
If the QR code is very small compared with the rest of the image, create a copy and crop closer around the code while leaving its full edges visible.
4. Try Google Lens instead of the Gallery app
If your manufacturer's Gallery app does not detect the code, open the same screenshot in Google Photos and use Lens.
5. Update Google Photos
An outdated or malfunctioning app can cause recognition features to behave incorrectly.
6. Clear the Google Photos cache
If Google Photos or Lens is behaving strangely, you can safely try clearing its temporary cache.
Go to:
Settings > Apps > Google Photos > Storage & cache > Clear cache
If you are unsure about the difference between cache and app data, read our guide to clearing Android cache without deleting data.
If Google Photos repeatedly freezes or closes instead of scanning the image, use our Android apps keep crashing troubleshooting guide.
Can You Scan a Wi-Fi QR Code From a Screenshot?
Yes. QR codes can contain Wi-Fi network information as well as website links, contact details, text, and other data.
If someone sends you a Wi-Fi QR code:
- Save or screenshot the QR code.
- Open it with Google Photos and Google Lens.
- Allow Lens to recognize the code.
- Review the Wi-Fi network information shown.
- Choose the available connection action if you trust the network.
Do not connect to an unfamiliar network simply because someone sends you a QR code.
Is It Safe to Scan QR Codes From Screenshots?
Scanning the image itself is not the main risk. The important part is what the QR code asks your phone to open or do afterward.
A QR code can send you to a website, start a download, open an app, provide network information, or perform another supported action.
Before opening a detected link:
- Look at the website address first.
- Watch for misspelled or suspicious domain names.
- Do not enter passwords or payment information on an unexpected page.
- Be especially cautious with QR codes received in unsolicited emails or text messages.
- Do not install an unexpected APK or unknown app because a QR code tells you to.
Samsung also recommends scanning only QR codes from trusted sources because codes can lead to unsafe websites or unwanted downloads.
