IT Home reported on October 27 that tech outlet MacRumors published a post yesterday (October 26) noting that Apple's first foldable iPhone Duo lacks the “Eye Contact” option in its FaceTime settings, so users cannot get the gaze correction the feature provides during video calls.
Citing the post, IT Home said the “Eye Contact” feature was first introduced with iOS 14. Designed mainly for video calls, it uses machine learning to adjust the image of a user's eyes so the other person feels the user is looking at the camera.
The feature has previously been available on a wide range of iPhones, including iPhone SE models, which use Touch ID fingerprint authentication and do not have Face ID.
The outlet has now confirmed that iPhone Duo does not offer the setting. Forum user TwoBytes first noticed that their gaze looked “a little off” during a FaceTime call, then found no corresponding control in the settings menu.
The report's analysis suggests that the issue may not stem from iPhone Duo's lack of Face ID or a TrueDepth camera, because iPhone SE also lacks that hardware yet supports the feature.
A more likely reason is the position of the Duo's under-display camera on its inner screen: the camera is on the right side of the screen, away from the central area where the other caller's face usually appears. Compared with the smaller vertical offset between the camera and the user's line of sight on a regular iPhone, the Duo requires correction for a larger horizontal offset, making implementation more technically difficult.
The foldable design also makes the issue more complex. The camera's position relative to the user's line of sight changes depending on which screen is used and whether the device is folded. One indication of this is that Apple has already restricted another gaze-based accessibility feature, “Eye Tracking,” to use only when the Duo is fully unfolded.
MacRumors said it had contacted Apple for a technical explanation. As of publication, Apple had not publicly explained the specific reason the feature is missing or said whether it would add it in a future system update.
