App return

as I said.. locate the app in the alphabetic list or in the search bar..

then tap&hold until it highlights and kinda pops up.. then drag, it'll pop back out onto your Home Screen

from your Home Screen, swipe left until you get to the App Library.

swipe downward and you'll get an alphabetical list of all your apps.

Scroll down to Phone or type it in the search bar

tap/hold/drag and it'll pop out to your Home Screen
