Today while I was on a video call with family using WhatsApp I noticed video effects when I used one of the signs. Then when I dug deeper to check i realised that it was a feature from iOS. If WhatsApp was end to end encrypted how are apple able to do this?

It takes place in the camera, not in WhatsApp. So those emojis and stuff are added in by apple, into the video that’s supplied to WhatsApp.
