iPhone 11 What are the authorized manufacturer/s for iPhone 11's Screen
Apple does not approve any brands for direct to consumer sale of Phone parts. They recommend complete service in an Apple Store or an AASP (Apple Authorized Service Provider Program). Parts alone don’t make the repair successful.

However, it can be cheaper to replace the screen at home. Keep in mind that you won't get any Apple &quot;free&quot; warranty replacement after your repair. Also, True Tone will be disabled on the phone - even if you use Apple &quot;original&quot; or “equivalent” screens.
I recommend iFixit parts, they come with great tools and the screen is of good quality - I ordered iPhone 11, 8 and XR screen parts without any problems.
