Hacked iPhone 11

Hello,

In addition to LatriciaP's comments, consider:

It is very unlikely that your phone was actually hacked. Modern iPhones are very secure and difficult to hack.

Instead, what usually happens is that someone tricks you into providing your login information via a phishing scheme and gains access to your data. This can give the false illusion of your phone actually being hacked.

If you think that this might be the case, change any relevant passwords immediately.

If you think that you might have a "managed" device, see this:

Good luck.

Does your iPhone indicate in red letters that it is supervised at the top of the page when you open your System Settings app? Are there any configuration profiles installed? Search for profiles in System Settings. Use Apple's Configurator App on a Mac and pair it with your phone and review the info that it gives for your device you can use Export...Info to get it as a csv file.
