"Apple has published a new support document entitled ,bout genuine
iPhone displays in which it confirms new warnings will be issued to buyers
of the iPhone 11 (guide), iPhone 11 Pro (guide) and iPhone 11 Pro Max
(guide) if they don't use an official Apple certified technician to repair
or replace a damaged display. And this could have serious financial
implications. "
"even if a genuine Apple display is used by your repairer, you will
receive the warning message if the technician didn't purchase their tools
from Apple."
"As you might expect, Apple tools are significantly more expensive than
third-party ones which push up running costs and, in turn, push up prices
for the customer."
