warranty is expired

You can't do anything with Apple (since AppleCare+ can be subscribed within 60 days from the date of purchase).

You can contact your insurance company and ask them if they can offer any kind of service about your iphone.

WIth your iPhone's warranty expired, any service required will come at the "out-of-warranty" repair rate. There is no option, at this point, to extend it ... unless you originally purchased an AppleCare+ extended service plan with the phone.
