iPhone Duo gains fake left bezel to boost case compatibility

TL;DR
A new display option called Shift Left Edge in the iPhone Duo adds a black fake bezel on the outer left edge to improve use with cases that partially cover the display. When enabled, it widens the left border and shifts content away from the folding edge; Apple notes it’s for cases that partially cover the left edge and a short demo suggests the effect is noticeable. Apple ships two first‑party cases at launch (Duo Case and Duo Folio with Kickstand), but the feature could also help third‑party rugged designs. The iPhone Duo goes on sale October 23, 2026.
