Whatsapp on desktop because it feels more "Native" to the computer and is an actual App, if you know what I mean. Not that whatsapp needs strong computing power I just prefer actual apps than web apps. SOLVED - Unable to scan the Whatsapp web QR code as it has broken and is not scannable as in the below image. Working fine in small size monitor but as I moved to 24 inch QR code is not looking proper. 10 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! So maybe a fix for some of you. I uninstalled whatsapp and downloaded whatsapp business app and got the code to verify phone number then uninstalled whatsapp business and went back to whatsapp and reinstalled it and got the code and all working. I got the code through sms. This was on android so not tested with iPhone. Hope this is a fix for you all.
