QR codes have become an integral part of everyday life: from paying for purchases to authorization in Wi-Fi networks. But not all users Android know that special applications are not always needed to scan them. Modern smartphones can recognize QR directly through a standard camera - just point the lens at the code, and the system itself will offer to follow a link or perform an action.
In this article we will look at all possible ways to scan QR codes on Android from built-in functions to third-party utilities. You will learn how to enable recognition in the camera settings, which applications are best to use for older devices, and what to do if your smartphone does not see the code. We will also talk about hidden capabilities of Google Lenswhich allow you not only to read QRs, but also to translate text from them in real time.
It doesnโt matter if you have a flagship Samsung Galaxy S24 Ultra or budget Redmi 12 โinstructions are suitable for any devices on Android 8.0 and newer. If your phone runs on an older version, donโt worry: we have prepared a separate section with solutions for such cases.
1. Standard camera scanning: does it work on your Android? Beginning in 2018, Google added built-in QR code recognition directly into the app. However, not all manufacturers enable it by default. To check if your smartphone supports this feature:
Starting from Android 9 Pie (2018), Google added built-in QR code recognition directly into the application Camera. However, not all manufacturers enable it by default. To check if your smartphone supports this feature:
- Open the application
Camera. - Point the lens at the QR code (distance - 10โ30 cm).
- If a notification with a link or suggestion appears at the bottom of the screen actions (for example, "Open example.com"), then the function works.
On some devices (for example, Xiaomi or Oppo) you may need to enable the option manually. To do this:
- ๐ง Go to
Camera settings(gear in the application interface). - ๐ Find item
Scanning QR codesorGoogle Lens. - ๐ Activate the switch if it is turned off.
Important: On devices with custom shells (for example, MIUI or One UI) the path to the settings may be different. If you do not find the item you need, try updating the application Camera via Google Play.
โ ๏ธ Attention: On smartphones Huawei without Google services (for example, Huawei P50 s HarmonyOS) standard scanning through the camera may not work. In this case, use the application Huawei Lens or third-party scanners.
2. Google Lens: hidden capabilities for working with QR codes
Google Lens is an artificial intelligence-based tool that can not only scan QR codes, but also recognize objects, translate text, and even solve mathematical problems. To use it:
- Open the application
Camera. - Tap on the icon
Google Lens(usually located on the right in the interface or in the shooting modes menu). - Point the camera at the QR code. Lens will automatically scan it and show the result.
If the icon Google Lens is not in the camera, install the application separately from Google Play. After installation:
- ๐ฑ Open
Google Lensas a separate application. - ๐ธ Click on the camera icon in the lower right corner.
- ๐ Point the lens at the QR code.
The advantage Google Lens over a standard scanner is the ability to work with damaged or partially erased QR codes. Google's algorithms try to reconstruct missing code elements, which increases the chances of successful reading.
If the QR code does not scan, try turning on the flashlight or changing the camera angle. Sometimes glare or shadows interfere with recognition.

It does not require an internet connection to recognize codes. However, to open links or download additional information (for example, when scanning Wi-Fi QR), you will still need the Internet.
5. Problems when scanning QR codes and their solutions
Sometimes QR codes are not scanned even on modern smartphones. Here are the most common problems and how to fix them:
| Problem | Possible cause | Solution |

Never scan QR codes promising โfree moneyโ, โprizesโ or โexclusive contentโ. This is 100% scam.
If you have already clicked on a suspicious link:
7. Additional features: generating and editing QR codes
In addition to scanning, Android you can create your own QR codes. This is useful for:
To generate, use:
For business tasks, services like QRStuff or Unitag are suitable - they allow you to create dynamic QR codes (you can change the link without generating a new code) and track the number of scans.
To ensure that the QR code scans well, use contrasting colors (black on white) and a minimum size of 2x2 cm. Avoid stretching or compressing the image - this may break the structure of the code.
FAQ: Frequently asked questions about scanning QR codes on Android
My phone does not scan QR through the camera. What to do?
First, check whether the function is enabled in the camera settings (see section 1). If it is not there, install Google Lens or a third-party scanner. On very old devices (up to Android 6.0), you may need to update the firmware or use online services.
Can you scan a QR code from the screen of another phone?
Yes, but there are nuances:
- Make sure the screen brightness is at maximum.
- Turn off auto-brightness - it can darken the code.
- If the code flickers, take a screenshot and scan it as a photo.
How to scan a QR code if the camera is broken?
There are two option:
- Take a photo of the code on another device and upload the photo to an online scanner (for example, ZXing).
- If the QR code is static (for example, a sticker), use a webcam on a PC with a scanner app.
Why do some QR codes open the wrong link?
This could be:
- Generation error โ the code was created with a typo in the URL.
- Redirection โthe link leads to an intermediate page (often used in advertising).
- Virus โ scammers replace legitimate codes with their own. Always check the address before going.
