Why I can't scan the WhatsApp QR? Why I can't scan the Whatsapp QR?


I reinstalled WhatsApp 
I already have the WhatsApp Web Option 
I put it to scan but it just doesn't scan it.
I Installed a QR Scanner app and it works perfectly.
I uninstalled the QR Scanner app to see if that was the issue and
still doesn't work.


My phone is a Samsung Galaxy Ace.
SOLUTION

Okay, first of all - you have to scan the QR-Code with the scanner that is built in WhatsApp. Not with some 3rd-party scanner-app. Click on "Whatsapp Web", then the scanner opens immediately.

BUT - apparently there is a problem with devices that have a display smaller than 4 inches!

Like with my Sony Xperia Go (3,5 inches), I can't tap on the "OK, got it"-button to make the instructions of the built-in-scanner go away.

That's it. They will have to solve this problem in a later version, I guess.
