Find a blank area on your home screen and briefly scroll up with a finger. This should open your app menu, listing all apps installed on your phone. On the upper right, tap on the three dots and select Sort and make sure that it's set to Alphabetical. Then, scroll left until you get to apps starting with a P and find the Phone icon. Press and hold the icon and drag it to the top of the screen until the app menu disappears. You can now drag it back down to where you want it on your home or app screen and let it go. For this to work, your home screen must be unlocked in Settings.
