What Does No Valid QR Code Detected Mean?
When you go to WhatsApp Web on a Web browser, it provides you with a QR code that needs to be scanned with WhatsApp app on your phone. The QR code is a type of barcode that contains login information that is only for your account to use. So when you receive ‘No valid QR code detected’ it means that the WhatsApp application you have on your mobile is not reading the QR code that is appearing on the screen.
In most cases, this message doesn’t mean that something is seriously broken – it just means that the process of reading the QR code didn’t go as expected. It could be a problem with the lights, the camera, the screen display or with a temporary hitch between the phone and the browser.
Common Reasons for Encountering the Error
There are a number of reasons why WhatsApp Web would say that the QR code is not valid:
- On the browser side, the QR code was not fully loaded.
- Your phone’s camera was unable to read the code (blurry/smudged/low lighting)
- Zoom levels of browsers were altered and so the code is not clear.
- You had opened WhatsApp Web in a bunch of tabs and this piece of code expired.
- This phone or browser connection is not stable/ slow.
Understanding these common causes can help you to troubleshoot quickly rather than guess what is wrong.
Step-by-Step- How to Solve the Error
Below are the steps on how to get rid of “No valid QR code detected” on WhatsApp Web:
1. Refresh the AD WhatsApp Web Page
Sometimes the QR code simply would not load properly. This is often a refresh of page by hitting the refresh button on the browser. There should be a new QR code – and this time your phone may well recognise it immediately.
2. Test Your Internet Connection
WhatsApp Web requires that your phone and your computer have an internet connection. If either one of the devices is weak or not sturdy enough the QR code may not load properly.
Try this:
- Switch from wifi data to telephone data in your phone
- Change nthe etwork in your computer’s Wi-Fi
Once you have a stable connection the QR code will be loaded with no discomfort.
3. Avoid Browser Zoom
If the zoom setting is too high or too low for your browser, then this will cause the QR code to be distorted so that your phone camera cannot read it. Reset the zoom to 100% by pressing:
- Ctrl + 0 (Windows)
- Cmd + 0 (Mac)
This is to make sure that the QR code turns out to be the original size.
4. Wipe the Lens from your Phone Camera
A smudgy/dirty camera lens can cause WhatsApp on your cell phone to have trouble trying to find the QR code. Take a moment and wipe the lens gently – even a small amount of frit can cause results that are not recognized.
Once you have vacuumed the lens clean, open up WhatsApp on your phone, point your phone at the QR code and try again.
5. Make Sure That You Have the Right WhatsApp Screen.
Some of the users mistakenly open wrong screen on their phone for scanning. Make sure that you’re in WhatsApp’s “Linked Devices” section:
- Open WhatsApp on your phone
- Touch the menu (3 dots in top right)
- Select Linked Devices
- Tap Link a Device
- Point and hold your camera over the QR code
This is a critical step to make sure that scanning works.
6.Reopen WhatsApp Web
If you have done the above and it still isn’t working, then try closing the browser tab/window altogether, and open up a new browser tab and go to web.whatsapp.com again. Sometimes there will be a glitch in the browser that is temporary and can cause a failure of the QR code.
7. Try a Different Browser
If your current browser still will not work, try putting the QR code into a different browser. For example if you’re using Chrome and if you get the message, try Firefox, Edge or Safari. This can help if you’re having a problem with your original browser or if it is blocking some features.
8. Updating Whatsapp application and Browser
Along with the outdated versions of your browser, even WhatsApp is sometimes the source of unexpected problems. Make sure:
- WhatsApp is updated on your phone
- Your browser is updated with the latest version
- After being updated, retry the process of linking
