Figured out solution..... Had Chrome Dark Mode app turned ON in laptop.. and even thought it is perfectly bright and clear for the scan.. the phone won't detect unless it is turned off.
Solved! Go to Solution.

Thanks for posting. Does this only happen in the Whatsapp QR code scanner? How about other apps with a QR code scanner? Try clearing the app's data and cache by going to Settings > Apps & Notification > See All Apps > Whatsapp > Storage > Clear Cache and Clear Storage. This might log you out of the app and reset the settings on the app.

That is good to hear and thanks for sharing the solution. I would suggest leaving this post on just in case there are other users who might experience the same problem with their QR code scanner.
