Apple's iPhone Duo includes a hidden "Shift Left Edge" display setting that adds a black border to the left side of the screen to accommodate cases that cover that area while preserving iOS back swipe functionality. The setting was discovered by blogger Nicolas Lellouche in the Display & Brightness menu, and the device launches October 23.
Apple's new iPhone 18 Pro, iPhone 18 Pro Max, and iPhone Duo are available for pre-order, with various accessory brands offering cases and screen protectors. Major retailers like ZAGG, Nomad, Belkin, OtterBox, and others are stocking protective accessories, with ZAGG offering 20% off when purchasing two items.
