iPhone 7 Plus
'Contacts" icon and "Phone" icons have disappeared from face of my iPhone. I can access my contacts searching the App Store for "contacts' and selecting 'OPEN' on the contacts app. this allows me to phone numbers in my contacts list, but without access to my 'phone" keypad i can't call other numbers. Switching iPhone off and back on has no effect. How do I retrieve the missing icons?
