I have seen alternatives for most iPhones at this point, but checking all my usual spots I don’t see any third party screens, only refurbished ones, which are still quite pricey. That doesn’t mean there aren’t any, but they are more likely to be of questionable quality.
The iPhone 13 Pro is still a pretty new device, why not fix it and then resell it if you already have plans for a replacement? I know it’s not a small investment, but it’s still less than a whole new phone.
