Thanks to this client, you can easily read and write messages on your computer without checking your phone each time you get a notification. So, continue to implement the fixes below in that case.WhatsApp Desktop is the desktop version of WhatsApp, one of the world's most popular instant messaging clients. However, if the problem is limited to WhatsApp Web, you must investigate the issue further. The problem lies with the cell phone if it cannot scan any QR code. You can verify that by scanning another QR code.

If you keep your devices neat and clean, you should ensure that there are no other issues with your cell phone camera. Likewise, you should also keep the cell phone camera lens spotless, as a dusty lens would consider dust as part of the QR code, making it impossible to scan the code correctly. Moreover, make sure that your mouse cursor isn't on the QR code you are trying to scan. Hence, you can start troubleshooting by cleaning your monitor screen to ensure no large dust particles are blocking the way to scan the code properly.

If dust particles build up on your screen and disrupt any one of these squares, your cell phone camera won't be able to perform a proper QR code scan.

QR codes are a bunch of black and white squares.
