So very few phones are supported and they seem to need two cameras and other fancy stuff.
On the other hand Pokemon Go was around for a while and as far as I know worked with most phones. The known IKEA app also work fine on my older phone and there is other examples.
If I can live without spatial anchoring etc. and just want a simple virtual object/animation shown via the camera for other phones, can I then do that in Unity?
okay, I did found some tutorials on this. I was searching “insert in camera” like getting threads about the camera inside Unity lol. Search for make like Pokemon Go helps.
Vuforia offers a motion tracking solution that works on many Android devices when ARCore is not present. There’s a link to download the Unity installer for Vuforia under Player Settings > Android settings > XR Settings
