After updating the project at Vuforia 8 (Unity 2018.3.1f1) we have the problem of the front camera.
It turns upside down. We have not found any way to fix it.
To take a quick test. We have created a new empty project. Imported Vuforia, and created a simple scene with ARCamera and ImageTarget. We set the front camera as the main camera. In the editor it works correctly, but once in the iPhone, it turns upside down.
Others have had this problem?
Any ideas on how to solve?
