Autofocus

Hi i came across a problem I do not really understand. I used the Vuforia api to activate Autofocus in my Project like so: void Start()

{

CameraDevice.Instance.SetFocusMode(CameraDevice.FocusMode.FOCUS_MODE_CONTINUOUSAUTO);

}

(I checked, and the script is actually called)

This however did not make the Samsung S8 i was testing on focus continously like expected instead it stayed unfocused (probably focused at infinity).

When I moved this setting into an Update function it actually made the S8 Autofocus. The Autofocus of a different Android Phone (Huawei P20) did not respond to the workaround but had the same problem of not autofocusing the usual way. Testing on a S7 the Autofocus worked as expected (one call on Start() was sufficient).

Since most Vuforia features stop working with an unfocused camera this seems like a major issue. Any ideas on how to resolve this in a satisfactory way?
