How can i screen record on iphone for a whole day?

My brother has been hiding his phone and messages with some people and he’s still young so he doesn’t know what he’s doing and it’s very suspicious. For anyone that says this is an invasion of privacy no it’s not because whenever i ask to check his phone he gives it to me but i’m worried he’s hiding more when we’re not looking. When you screen record on phone it turns off instantly when u close the phone. Is there a way to stop it from turning off?

if you think your brother is doing something he shouldnt then tell your mother about it

How about you mind your own business and leave the parenting to your parents. If they believe he is mature enough to own and use a phone that is up to them.

How would you feel I'd someone was doing this to you?
