Spyware on iPhone

Not likely in only 5 minutes. Use the search and look for the app “cydia” - if it isn’t on the phone your phone probably hasn’t been hacked.

But if you have any doubts, or just for reassurance, restore the phone to factory settings, then restore a backup made before the incident happened.

1. Restore your iPhone, iPad, or iPod to factory settings - Apple Support - follow the instructions to restore using your computer, do not using Settings/General/Reset
2. Restore your iPhone, iPad, or iPod touch from a backup - Apple Support

To install tracking apps the phone must first be jailbroken. Cydia is the control app for a jailbroken phone, so if your phone doesn’t have it then installing tracking apps is not really possible.

One additional thing to check is in Settings/General/VPN & Device Management. Do you see any profiles? If not then no non-approved apps have been installed.
