Apple Cautions DIY and 3rd Party iPhone Screen Fixers
For the last few years, I've been replacing my own cracked iPhone screens because it's far cheaper than going to those kiosks in the mall and especially to the Apple store. All it takes is a cheap after-market screen off of eBay, a couple of special screwdrivers and a quick 5-minute tutorial video on YouTube and you're good to go. At least, that USED to be all it took. As Apple releases new phones, this practice is getting harder and harder to do.
They have cautioned that even if you've done the repair carefully and successfully, the phone's software might not interface with the new screen correctly afterwards. On the iPhone 11s, Apple has now installed software that can detect if your screen is an Apple screen or not and even sends you warning messages if not.
"The iPhone display is engineered together with iOS software for optimal performance and quality. A nongenuine display might cause compatibility or performance issues. For example, an issue might arise after an iOS software update that contains display updates."
As always, repairs whether by yourself or through a mall kiosk are at your own risk... And being that your iphone is worth $1K or more, it's a rather large one especially as our phones become more and more complex.
