To restart an iPhone SE (second generation) or newer model, press and hold the power button until the words “slide to power off” appear on the screen. Swipe the slider from left to right to shut down your iPhone. Wait about 20 seconds, then press and hold the power button again until you see the Apple logo flash onto the screen. Your iPhone will turn back on shortly after.

To restart an iPhone XR or newer, press and hold either volume button and the Side button until the “slide to power off” slider shows up on the screen. Then, swipe the power icon from left to right. After about 20 seconds, press and hold the Side button until the Apple logo appears on the center of the screen.

If you have an iPhone XR or newer model, swipe down from the upper right-hand corner of the display to reveal Control Center. Now, press the red lock button to enable screen rotation.

4. Update Your iPhone

If your iPhone Calculator is still not working, the next thing you can try is updating your phone to the latest version of iOS 17. Since Calculator is a native app, bugs and other technical issues within the Calculator app can usually be fixed by simply updating the iPhone to the latest version of iOS.

To update iOS, go to Settings and select General. Tap Software Update and check to see if there are any iOS updates available. If so, Download & Install the update and then try using the Calculator app again.

If you’re already on the latest iOS version and Calculator is still not working on your iPhone, move on to the next solution.

5. Reset All iPhone Settings

At this point, the iPhone calculator should be up and running. But if it still won’t work, then you might consider resetting your device. When you do this, iPhone Settings will be restored to their factory defaults but your files and data will be kept safe.

To reset all settings on your iPhone, go to Settings > General > Transfer Or Reset iPhone > Reset > Reset All Settings, enter your passcode, and tap Reset All Settings.

To reinstall Calculator, go to the App Store and tap on the Search tab located at the lower right-hand corner of the screen. Then, type “Calculator” into the search box and tap Search.

The Calculator app should be the top result. Tap the button to the right of Calculator to reinstall it on your iPhone. Since the Calculator app was previously installed on your iPhone, the reinstall button will look like a cloud with an arrow pointing down.
