QR codes have long ceased to be exotic - they are everywhere: from cafe menus to transport tickets and links to download applications. But what to do if the code needs to be scanned from the screen of another phone (or even from the same thing)? On Android this can be done in literally 10 seconds - and you donโt always need to install additional apps.
Many users mistakenly believe that to read a QR code you definitely need special application or a second gadget. In fact, modern versions Android (starting from Android 8.0 Oreo) have built-in tools, and for older devices there are workarounds. In this article we will look at all working methods from standard functions to little-known features that work even on budget smartphones.
If you have ever tried to take a photo of a QR code from the screen and received an โunrecognizableโ error, there is a problem not in the code, but in wrong approach. The fact is that most scanners are optimized for printed codes, and not for display. But there are proven tricks that solve this problem without unnecessary movements.
1. Built-in QR scanner in Google Lens (the fastest way)
Since 2019 Google Lens integrated into the standard application Camera on most Androidsmartphones (including Samsung, Xiaomi, Pixel etc.). This tool not only recognizes objects, but also does a great job with QR codes - even if they are displayed on the screen of another phone.
To use it:
- Open the application
Cameraon your phone. - Point the lens at the QR code on the screen of another device.
- Wait for the notification to appear "Tap to scan the code" (usually a yellow dot or code highlight appears).
- Touch the notification - the link will open in the browser or suggest an action (for example, add a contact or connect to Wi-Fi).
โ ๏ธ Attention: On some firmware (for example, MIUI from Xiaomi) Google Lens may be disabled by default. To activate it:
- Open
CameraโAdditional(orMore). - Select
Google LensorLens. - Allow access to the camera and photos if prompted.
If Google Lens does not recognize the QR from the screen, try reducing the brightness of the second phone to 50% - this will reduce glare and improve readability.
This method works on 90% of modern Android smartphones without installing additional applications. The exception is devices with heavily reduced firmware (for example, some models Huawei without Google services).
2. QR scanner in Google Photos (if the code is saved as an image)
If a QR code is displayed on the screen of another phone, but you cannot scan it immediately (for example, due to glare or small size), take a screenshot of the code and use the built-in scanner in Google Photos. This method is suitable for codes that:
- ๐ฑ Displayed on the screen of another device (including your own).
- ๐ผ๏ธ Saved as an image in the gallery.
- ๐ง Sent in messenger (WhatsApp, Telegram etc.).
Instructions:
- Take a screenshot of the QR code (press
Power + Volume Downat the same time). - Open Google Photos and find the screenshot you took.
- Tap the icon Google Lens (icon with a multi-colored square) in the bottom panel.
- Application automatically will scan the code and offer to follow the link.
โ ๏ธ Attention: If you have a third-party application installed for the gallery (for example, QuickPic or Gallery Go), Google Lens may not be displayed. In this case, open the screenshot through the standard application Photo from Google.
Why does scanning in Google Photos not work?
If Google Lens does not recognize the QR in the screenshot, check:
1. Image quality - the code must be clear, without blur.
2. File format - supported only .jpg, .png, .webp.
3. Application settings - in Google Photos โ Settings โ Google Lens The option must be enabled Scan QR codes.
3. Standard "Camera" application (for Samsung, Xiaomi, OnePlus)
Many manufacturers build a QR scanner directly into a standard camera. This is convenient because it does not require additional actions - you just need to point the lens. Let's look at how this works on popular brands:
| Brand | How to activate | Features |
|---|---|---|
| Samsung | Open Camera โ hover over the QR โ a notification will appear with link. |
Works on all models with One UI 2.0+ (starting from Galaxy S8). |
| Xiaomi | Open Camera โ swipe down for additional modes โ select QR scanner. |
On some models (Redmi Note 8 and older), the scanner turns on automatically. |
| OnePlus | Open Camera โ touch icons QR in the upper right corner. |
Available on OxygenOS 11+ (models OnePlus 8 and newer). |
| Huawei | Open Camera โ go to mode Additional โ QR scanner. |
On new models without Google, installation is required Huawei Mobile Services. |
๐น Important: If the scanner does not work, check whether the function is enabled in the camera settings. For example, on Samsung the path is:
Camera settings โ Smart functions โ QR code scanner.
โ ๏ธ Attention: On some budget models (for example, Realme C-series or Nokia 1.x) there may not be a built-in scanner. In this case, use the methods from the following sections.
4. Applications for QR scanning (if nothing works)
If the built-in tools are not suitable (for example, you have an old version Android or custom firmware), install one of the specialized applications. We tested the top solutions and chose those that:
- ๐ Work without the Internet (offline scanning).
- ๐ก๏ธ Do not collect unnecessary data (tested via Exodus Privacy).
- ๐ฑ Support scanning from the screen (including dynamic codes).
The best options:
- QR & Barcode Scanner (from Gamma Play) - minimalistic interface, no ads, supports
Wi-Fi,URL,vCard. - Kaspersky QR Scanner - checks security links before opening (useful for codes from unknown sources).
- Barcode Scanner (from ZXing Team) - open source, works on Android 5.0+.
๐น How to scan from the screen through the app:
- Install one of the applications above.
- Open it and point the camera at the QR code on the screen of another phone.
- If the code is not recognized, reduce the brightness of the source screen or turn on
Reading mode(if available).
๐ Make sure the code is not from a suspicious source
๐ก๏ธ Use Kaspersky QR Scanner to check links
๐ต Do not scan codes from other people's devices without consent
๐ Check the URL before going (must start with https://)-->
โ ๏ธ Attention: Avoid applications with names like "Super QR Scanner Pro" or "Fast Barcode Reader" โthey often contain hidden advertising or requests for unnecessary permissions (for example, access to SMS).
5. Screenshot + online scanner (if the phone does not recognize the code)

| Problem | Possible reason | Solution |
|---|---|---|
| Code not recognized | The brightness of the source screen is too high | Reduce the brightness to 30-50% or turn on Dark theme. |
| The scanner โdoes not seeโ the code | Code dynamic (changes every second) | Take a screenshot and scan a static image. |
| The application displays an error | QR is damaged or non-standard format | Try an online scanner Inlitere Research (recognizes damaged codes). |
| The camera does not focus | The distance to the screen is too small | Move the phone 15-20 cm or use macro mode (if available). |
๐น Advice for older phones: If you Android 5.0 or lower, try the application QR Droid โit is optimized for weak devices and works without Google Play Services.

Why canโt some QR codes be scanned from the screen?
The point is display technologies - many screens (especially AMOLED) use PWM pulse width modulation, which can distort the QR code for the camera. Solution: enable the source mode For reading (if available) or reduce the screen refresh rate to 60 Hz.
