Delta YoWhatsApp is a modified and advanced version of WhatsApp. You won’t exactly seek it off the Play Store which you might have gotten when you might have downloaded WhatsApp. Considering that these versions aren’t released out by the actual developers, they aren’t accepted on the Play Store though some have mentioned that they have appeared on the Stores once in a while. The thing is, these versions have certain enhancements in their code which they were developed upon to give the user advanced features which aren’t provided by the original version of the platform. From here you can easily install the apk on your device to get the amazing features that it offers to the users.
