I think my LEGO english probably make anyone confused ,so just take a example:
I'm using desire 820s now.
One day,I suddenly want to replace my phone's display with iPhone 11's OLED display.
Here's the question:
If we don't care I actully can't put it into my phone in physical,and I dont care about face ID, I also upgraded to Android Pie after I replaced display, What'll happend?
