I am currently developping a Unity based mobile application for android and iOS. I'm using the ground plane feature of Vuforia. Overall things are working. I am having a problem though on specific devices.
The issue appears on a Samsung S7 Edge (I'm sorry I don't know if it is Exynos or Snapdragon model, it belongs to a customer), I gasered the log though, and it contains the message "D Vuforia : Error: Unknown Tracker type could not be initialized.". Apparently this prevents the whole PlaneFinderBehaviour to work as the aim_target doesn't show up in that case.
So the information I have :
* Samsung S7 Edge phone model
* Android 7.0
On another S7 Edge (running Android 8.0) everything works as expected. Could it be that the one not working is a Snapdragon model and the one that is is an Exynos ?
I am not quite sure by the way, is the ground plane feature using ARCore ? If it is, is it mandatory to have ARCore support on the phone in order to use the Vuforia Ground Plane feature ?
