We are experiencing an issue related to DepthData from the TrueDepth camera on a specific device.
On December 1, we tested with the complainant’s device iPhone 14 / iOS 26.0.1, and observed that the depth image is received with empty values. However, the same implementation works normally on iPhone 17 Pro Max (iOS 26.1) and iPhone 13 Pro Max (iOS 26.0.1), where depth data is delivered correctly.
In the problematic case:
TrueDepth camera is active
Face ID works normally
The app receives a DepthData object, but all values are empty (0), not nil
Because the DepthData object is not nil, this makes it difficult to detect the issue through software fallback handling.
We developed the feature with reference to the following Apple sample: https://developer.apple.com/documentation/AVFoundation/streaming-depth-data-from-the-truedepth-camera
We would like to ask:
Are there known cases where Face ID functions normally but DepthData from the TrueDepth camera is returned as empty values?
If so, is there a recommended approach for identifying or handling this situation?
Any guidance from Apple engineers or the community would be greatly appreciated.
Thank you.
