Apple's iPhone Duo has a Display Setting That Users Cannot Change Later
Antara
A Surprising iPhone Duo Limitation: Apple's first foldable iPhone Duo has a surprising limitation: users cannot change Display Zoom after completing the initial device setup.
Display Choices During Setup: During setup, an Appearance screen asks users to choose how large text, icons, and interface elements should appear on screen.
Three Display Size Options: Choose Default, Medium, or Large to set how text, icons, and other interface elements appear before reaching the home screen.
How Other iPhones Handle It: On other iPhones, users can revisit Settings, open Appearance, and select Display Zoom to adjust the interface after initial setup.
The Missing Display Zoom Option: On iPhone Duo, however, the Display Zoom option disappears from Settings once users finish the initial device setup completely.
The Issue Continues on iOS 27.2: MacRumors confirmed the missing option on an iPhone Duo running Apple's latest iOS 27.2 software, according to its report.
A Factory Reset is Required: An Apple Support senior advisor reportedly said changing the choice requires erasing the device and setting it up again entirely.
Text Size Can Still Be Changed: Users can still adjust text size through settings, but this does not fully replace Display Zoom's wider interface scaling changes.
Will Apple Fix This Issue?: Apple has not publicly explained the omission, leaving buyers unsure whether a future software update will restore the missing control.
