Bad cylindrical marker recognition on 13 and 14 iPhones

Making a project with Vuforia's cylindrical markers. Markers are relatively small ~60mm * 15mm It turns out a strange situation. On the latest iPhone models (13 and 14), the marker is very poorly recognized. On models X and 11, on iPads, recognition is much better. Visually, the problem is that when moving away or approaching, the camera's focus on the marker is lost, and the image is blurred. Maybe someone faced a similar situation? I would be grateful for any answers and advice :)

I'll try to stable recognize a small cylindrical marker. Stable recognition on all distance. iPhone(13 or 14 model) loses focus when approaching or moving away from marker.

We've observed differences in the performance of continuous autofocus when running ARKit. By default, Vuforia Engine enables ARKit via Vuforia Fusion.

The same article references an API that allows an app to disable the Fusion feature, which on iOS devices will disable ARKit. You can use this to evaluate the performance differences in continuous autofocus between the ARKit camera and the legacy iOS camera.
