In 2020, Chinese BOE was supposed to be a supplier of displays for iPhone 12. The quality did not meet Apple standards so the contract was cancelled. Any displays that were produced were then used by Apple’s refurb program For replacement displays.
Samsung invented AMOLED mobile displays and is obviously the undisputed leader in quality, R&D, and technology.
Harsh, majority of the phone's parts are sourced in China and its assembled there.
Meh, Samsung is a manufacturing juggernaut but 'leader in quality'? Leader in manufacturing capability quality maybe, but professional reference displays are not using Samsung displays and its not because they are "too good".
Samsung did not invent AMOLED. They didn't invent Active Matrix systems nor did they invent the OLED panels, they didn't even come up with there use together. They "improved" on the AMOLED design for touch screen integration and trademarked it as "Super AMOLED".
Both the Nokia N85 and BenQ S88 were AMOLED phones on the market prior to Samsung first AMOLED.
Might not be true anymore more but LG was the "leader" in Super AMOLED display tech at one point, from a quality perceptive. V30 or V40 I believe.
And apparently Samsung is going to use LG to manufacture their large high quality OLED displays. Keep in mind Samsungs main focus for TV's is LCD....
Samsung Electronics is expected to ink a 3-trillion-won ($2.5 billion) deal with LG Display to buy organic light emitting diode (OLED) and liquid crystal display (LCD) panels next year, according to market analysts.

Aka Samsung OLED's can't meet their own quality control. Joking..reality is the cost for Samsung to setup operation to produce OLED's then the R&D required to make large OLED's as good as LG exceeds the cost of just buying them from LG.
This is a moot point anyway. Apple is the 'contractor' in this deal. They research and design the electronics to their own (Apples) specs and then contract an electronic manufacturer to build that design. Its not a Samsung display, its an Apple display that was built by Samsung. Any R&D and advance technology Samsung might have (outside the fab process) does not go into any Apples contracts. How could it? Apples LTPO/IGZO display with Pro-motion isn't anything anyone has made before and uses different materials, processes, and technologies.
A contractor not meeting quality control on several attempts is far from abnormal. Its unlikely Samsung had first runs that were phone ready either. They likely just have a better process for setting up for manufacturing Apple components plus they are familiar with them and know what they are looking for.
The end product will be indistinguishable because of Apples quality control over their components. And its fairly easy for a display because they're is a known calibration which Apples iPhone display always excels at usually ahead of AMOLED industry leaders when its comes to accuracy (when reviewed by professionals)...
