What is true of this model and changes how you fix it
- Still supportedThe phone can run iOS 26, so software support is not the reason to replace it; a worn battery is the repair that extends its life.
- The earpiece sound programApple ran a free service program for iPhone 12 and 12 Pro phones made between October 2020 and April 2021 whose earpiece module failed, leaving calls silent. MacRumors reported in October 2025 that Apple ended it, so a repair for a silent earpiece is no longer free.
- Green tint at low brightnessSome iPhone 12 displays show a green tint or flicker at low brightness in a dark room, which owners report on some panels and not others.
