iPhone 12 screen repair for an iPhone 6

I want to trade an iPhone 12 screen repair for an iPhone 6.

My iPhone 12's OLED screen randomly died. It now shows a green tint to it, with no content showing. I am not certain whether this is a hardware or software issue. I tried hard resetting it in all shapes and forms (believe me).

I read in one source that the earpiece might have to do with this but I don't have the capacity to experiment and find out.

I would be willing to trade my old iPhone 6 for the screen repair. It has a dead battery because I haven't used it in a few years, and a cracked screen.

Let me know if you are interested and can get the screen fixed.
