I have lost my Calculator icon. I can find it with Search, but no icon. What's up?

No need to reset, reboot, just open Apple Store and search calculator u can restore it

In case you didn't notice, you responded to a post that is over 5 years old now. I would hope that the problem was resolved long ago.

Launch tthe App Store on the phone. Tap on Purchased. Tap on Not on this phone. You should see it listed, unless it is already on the phone. If it's on the phone it will be on the All tab.

Search in the App Store, find the calculator by Apple and install.

That only made it worse and still no calculator.

Perfect. Thank you.
