Option 4: Get it fixed by a third-party unauthorized shop
So, you want to take your broken iPhone screen to an unauthorized third-party for a repair? You may want to read this first: Apple apologizes for Error 53 bricked iPhones and offers a fix. You may not save that much money by taking your iPhone to a third-party repair shop. Actually, it could become a nightmare, as they may break or damage something else in your iPhone when replacing the screen.
Consider that Apple may refuse to repair your iPhone altogether in the future, as you have voided the warranty by taking your iPhone to an unauthorized repair shop. If you have AppleCare+ it will definitely be safer and cheaper to let Apple fix your iPhone.
There are some good third-party repair shops and services out there and some tempting prices, but it’s smart to be cautious and do your homework. Look for reviews on any shop or service you’re thinking about using, and check what guarantees they offer with the work. Understand that if you go to a third-party, then your only option, if anything goes wrong, is to deal with that third-party.
