Y’all I’m new to Apple or I should say I took the time to look into Apple.. omg! My smart phone is too smart for me! Also.. why I’m the world does it give me a list of devices that I do not have?

We cannot check your device. Where are you seeing this list of devices? If it is in your iCloud account then, yes, someone may well be using your ID. Change your password immediately.

You should change your password immediately if you see devices that are not your own and then delete them from your iCloud account. As for learning to use your iPhone better you should constantly check the tips app and keep your iPhone up to date for new security updates.

I’m new to the new iPhones as well but I had an experienced used iPhone SE and that one actually is pretty basic and pretty user-friendly that’s a better model for you I don’t know but maybe should consider it if you’ve got more than one of the more advanced ones like a 11 or better the iPhone SE ease of use
