1. You'll need to first start with a home screen that's completely full of applications.
2. Next, choose the application that you want to hide and hold it down until the apps start wiggling.
3. Drag the app over an icon on the full home screen as if you're going to create a folder.
Create a folder and move WhatsApp there. Though the app is not hidden, it will give you some privacy so that others wouldn't spot it quickly.
