my Areatarget-application works fine in the simulator and recording but not on my android smartphone. The added 3D Objects (added as childs of AreaTarget) are never shown. It seems to me that the areatarget is never recognized. I have tried different Areatargets.
I am using Vuforia 10.4.4 and Unity 2021.2.7f1 and Samsung S8, S10+, Note 10+ (Android 12).
The log on the mobile device shows
Creating dataset: Vuforia/flur.xml/flur
Exception in callback: Failed to create AreaTargetObserver: FEATURE_NOT_SUPPORTED
In the same environment using the Vuforia Groudplane verything runs fine on Samsung S8 and S10+ but not for the Note 10+.
In the Area Targets test app my Area Target was working.
