Problem with your claim.
You buy a book. Not on contract. The PAPER is your property but NOT the text within, as that's protected by copyright. Your access to the text within the book is under the terms of the copyright; for example, you can't make copies of the text and sell that on. You CAN sell or pass along the book, but all the rights tied to the book go with it.
You buy a car. That car has a computer in it, with proprietary software protected by contract. You can scrap the software and install your own, but if the dealer's garage learns of this they can pretty much tell you YOYO.
Same with the phone as it contained copyrighted software.
See, when you buy something that contains copyrighted material in it, it gets...complicated.
