Basically, I want to buy an iPhone 15 512GB used for $400. The seller has stated that an “unknown part” message has appeared due to display replacement. They have also stated that everything else works fine like:
-Face ID
-True Tone
-Other features
Pictures were also provided and the replacement display looks good (true OLED Blacks and the seller also said that the display is high quality - seller has good reviews). Would it be okay to purchase it, since it’s in great condition otherwise, or not? People have said, that apple can disable parts in future updates. The price seems good though, since iPhone 15s with 512GB of storage cost around 600-700 in my area.
