Ensure You’re Scanning the Official WhatsApp QR Code
A crucial aspect of resolving this issue is ensuring you are scanning the correct QR code. WhatsApp restricts QR code scanning to its designated Web QR codes.
For non-WhatsApp QR codes, use the traditional scanning method on your iPhone or Android.
Update Your WhatsApp App
Outdated versions of WhatsApp may impede successful QR code scanning. To ensure your app is up to date, navigate to the Google Play Store (for Android) or the App Store (for iPhone). Locate the “WhatsApp” app and tap “Update.” If this option is unavailable, your app is already current.
Regular updates fix potential bugs and introduce new features, enhancing your overall experience.
Clear Your WhatsApp App’s Cache Files (Android)
Clearing WhatsApp’s cache files can be a helpful troubleshooting step for Android users. This process won’t result in the loss of chats or other data.
To execute this, close WhatsApp on your phone. Navigate to “Settings,” then “Apps,” and select “WhatsApp.” Within the app settings, go to “Storage” and tap “Clear Cache.” This action eliminates any corrupt cache files that might be causing the “No Valid QR Code Detected” error.
Clear Your Desktop Web Browser’s Cache
Sometimes, the issue may lie within the desktop web browser’s cache. Clearing this cache can potentially resolve the problem.
The process remains consistent whether you’re using Google Chrome, Mozilla Firefox, Microsoft Edge, or Apple’s Safari. Locate the browser’s settings, find the option to clear the cache, and restart the browser.
This action won’t erase your browsing history, saved passwords, bookmarks, or other data; the browser will rebuild this cache as you browse.
If the problem persists, try using a different web browser.
Use a Different Web Browser
Consider using an alternative web browser if the “No Valid QR Code Detected” error persists.
This step helps identify whether the issue lies with the current browser. For instance, if you’re using Chrome, switch to Firefox and attempt to scan the QR code.
If successful, it indicates that the initial browser may have encountered a glitch. To address this, you can turn off extensions, reset the browser, or reinstall them, depending on your device and browser type.
