Can you see your iphone settings history?

So recently a friend was on my phone and did something to my settings. I don't know what he did, and he won't tell me. So I want to know if there's anyway I can see what he changed

No but if it was serious you would notice.

No
Do you notice anything weird by chance?

Other than knowing your own settings & seeing what's changed, no.

I don't think so that it would be possible and if you need some advanced security, Leo Privacy would be the best.
