My camera icon used to be on my home screen and now it has disappeared on my home screen and I need step by step instructions on how to get it back to my home screen
1. Open your App Drawer (by tapping the button in the bottom Favorites Tray that looks like a grid of dots).
2. Look for the Camera app in your App Drawer.
3. Long-press the Camera app icon, then drag and drop it back to your homescreen.
