“Only technicians who have completed Apple service training and who use Apple genuine parts and tools should replace iPhone displays. These service providers include: Apple, Apple Authorized Service Providers, or Independent Repair Providers using genuine Apple parts. Replacements not performed by Apple, authorized service providers, or certified technicians might not follow proper safety and repair procedures and could result in improper function or issues with display quality or safety. Apple displays are designed to fit precisely within the device. Additionally, repairs that don’t properly replace screws or cowlings might leave behind loose parts that could damage the battery, cause overheating, or result in injury.”
Apple says that several issues linked to multi-touch, brightness, and color displays may occur when “non-genuine screen components” are used. A display message will appear on the iPhone 11, Pro and Pro Max to notify users if a replacement display cannot be verified as genuine.
The firm claims that this notice will not influence the capacity of customers to use the device and will appear on the lock screen for the first 4 days and in the Settings app for 15 days after repair. After this period, you will find the notice in the Settings > General > About section.
