  8. Hi, i recently bought a used iPhone X and i noticed the lack of true tone option only after few days, so i supposed that it is not the original display, even if it seems an oled one and it performs really well, in terms of colours and response. Is there a way to determine what kind of display is (refurbished, aftermarket, etc)? How can i be sure that the front camera is the originale one? Can i restore the true tone functionality, not having access to the original display? Where i can download JC Assistant Software from? Thanks!
