Adjust iPhone Duo's Outer Display to Accommodate Your Case

On iPhone Duo, Apple includes a display setting for cases or frames that partially cover the left edge of the outer display. It's called Shift Left Edge, and it insets the display edge so that on-screen content isn't hidden beneath the case. We first covered the setting in September, and Apple has since documented it, revealing that when you fit Apple's official iPhone Duo Case, a prompt automatically appears on the display to direct you to the setting. However, you can also turn it on manually at any time for third-party cases. How to Turn On Shift Left Edge Open the Settings app on your iPhone Duo. Tap Display & Brightness. Toggle on Shift Left Edge, then tap Enable in the prompt that appears. The final prompt will tell you that your iPhone Duo needs to restart to apply the setting, but it's not a full reboot, and you'll be returned to the same settings screen after a brief black screen. If you subsequently swipe up to the Home Screen, you'll notice a narrow black border on the left side of the outer screen to accommodate the front portion of the case, leaving no content obscured. Apple offers two official cases for its new foldable: the aforementioned iPhone Duo Case, and a Folio with Kickstand that causes no such display occlusion.
