cannot scan QR code for login whatsapp web version using 3 inch display phone, cannot scan QR code for login. any idea to solve this?
Problem is you can't do it with a display that is smaller than 4 inches... Normally, the built-in scanner in Whatsapp has an "OK, got it" button at the bottom of the instruction screen that blocks the camera. On my 3,5 inch model, this button is cut off, so I can't remove the message.

No Chance.
