Is iOS 11.2 fixed?

As in what exactly? You didn't give us an issue.

If you're asking if iOS 11.2 has been officially released, then yes.

I have iOS 11.2 on two iPhones and two iPads without any problems, so there is nothing that needs fixing. Please describe your problem and we will try to help you.

What do you understand under being "fixed" when you don't tell us what has to be done so?
