We had lost the Contacts Icon on my wife's iPhone. Contacts still worked inside the telephone app so I knew the data was not lost. Dominic23's #1 fix worked. Contacts was in the app list. I moved it onto her front page.

We think the way to lose the Contacts icon is try to put it into the tray at the bottom of the screen when there are already four icons in the tray. I tried and lost the Contacts Icon again, however, of course, we now knew how to recover it.

Have you tried searching for the app?

Search on your iPhone, iPad, or iPod touch

If necessary, do a backup and try a factory reset. Then restore from your backup.

Restore to Factory setting.      

Restore - If you see an error when you update or restore your iPhone, iPad, or iPod
