Q: My whattsup icon has disspeared. How do I recover it?

Hi LuamS,

Welcome to the Apple Support Communities! I'm sorry to hear that you are having this issue with your iPhone. If you are not seeing or are having troubles locating a specific app on your iPhone, you may want to see if it has simply been moved or misplaced in a different location. You can do so by using the search functions to try and locate the app, as outlined in the following article:

If you are unable to locate it on your iPhone, you may need to redownload it from the App Store, as noted here:
