Then we will show you how you can do it for both Android and iOS operating systems …
In this operating system we will have to use the 3D Touch technology of the iPhone. When your phone is locked and WhatsApp notifications arrive, leave your finger by clicking on the notification and voila! Immediately the Keyboard opens for you to respond without changing your connection time, appear online or you get the terrifying blue popcorn.
In the case of Android, what we will have to do is to scroll down the notification of the system that includes the WhatsApp message, then we press the option that says Reply or Reply to, and once we place the message we just have to press the cone sending.
