I want to remove the back cover of my iPhone 11 it trip off please I need a solution to this

Sorry, you’re not making much sense.

You can’t remove the back cover. To begin with, the iphone is not user serviceable. Secondly, the internals of the phone are laminated to the back. Try to take it off and you permanently bork the electronics inside.

If it’s broken or damaged, make an appointment at the Genius Bar of your local Apple Store.
