Hi guys,
Is there any known issue with AR on Android ?

I’ve made some billard table using AR, all works fine.
I’ve started a mini-soccer table AR app, starting from the billards app so the puzzles and so on are the same, but it does not work on Android (iOS is fine) : The photo goes in camera/vedio mode, but the “show prompt” “move around” does not shows itself.
Strange : when i close the AR mode (not with exit AR button as i did not be able to go in AR, but with the exit full screen button, the “move around” button is shown over the scene, and very strange, the 3D scene area (iframe ?) looks shifted, like projected onto a plane in perspective…

Any idea ?
PS : the AR puzzles are from the default “augmented reality” app.
