I have recently started testing ARKit on an iPhone 16 Pro and I have noticed that the AutoFocus reaction on this device is much slower than other devices. For example, if I point the camera to a close object AutoFocus takes 4-5 seconds to stabilize, the focal length is adjusted very very slowly. In some cases (although this is rare) AutoFocus seems almost stuck and requires a bit of device movement to trigger.
This is quite problematic when using some ARKit features like Image and Object detection as the detection algorithms struggle with out-of-focus images.
This problem is limited to ARKit. AutoFocus is significantly more responsive when the standard AVFoundation Camera API is used.
This behavior is easy to reproduce with any of the ARKit samples like https://developer.apple.com/documentation/arkit/arkit_in_ios/content_anchors/tracking_and_visualizing_planes
Is anybody else experiencing this problem?
