Apple has added a new setting to the iPhone Duo that allows users to move the content on the outer screen away from the foldable edge, a move seemingly designed to improve the phone's compatibility with certain types of cases. Blogger Nicolas Lellouche discovered this option while testing the phone, where it appeared in the display settings under the name "Shift Left Edge." When enabled, the system adds a black bar to the left side of the outer screen, effectively creating a faux edge that pushes the screen content away from the fold.
