Just buy another broken unit and pull the parts that you need. Please don’t expect my poor Apple company to have to keep track of old parts - Just doing that wastes man hours and transport resources and takes up space. For what? - A few cheapskates who want to keep an old iPhone 5 running? What am I missing here really. You can spend a couple hundred dollars fixing a $50 phone if you wish. But do not force Apple to accommodate this.
You can even spend 10000$ to fix the 50$ iPhone, but it won't show any picture on the screen because greedy MULTI BILLION $ company APPL prohibits that in their software. Talk about eWASTE.
Good chinese 3rd party screens for an iPhone 5 are super cheap. Because Apple never implements good quality (could hurt their margin).
