Video: How to change dp in WhatsApp
If you want to change the display picture or profile picture in WhatsApp then what you do is go ahead and open "WhatsApp". Tap on "Settings". Now this one at the corner here is the display picture or what we call now as profile picture of my WhatsApp application. So, if I want to change it, I will tap here. I will tap on this "Edit" here. Then I will select "Edit". I have two options. Either I can take a new photo or I can choose photo from the photo gallery.
So, let me choose photo from the photo gallery. Choose photo and then I will go to the picture which I want to set as the display picture. For example this one here. Now from here you can zoom in or you can zoom out. You can move photo to the left or to the right. After making adjustment, select "choose" at the bottom and now the profile picture or the display picture in WhatsApp is set..
