How to I fix an iphone that scammers install teamviewer on?

Also when connecting to an iOS device, only screen sharing is available, which means that a remote side is not able to control an iOS device. On top of that, unattended access isn't available on iOS, which means that only when you accept their access on your iOS device, they can connect to your iOS device.
