Kind of a duplicate topic to a previous post of mine but I've pinpointed the exact problem:
My ArCamera with Ground Plane moves around just fine when using the editor (and ground plane emulator marker), but as soon as I put it on device (Galaxy Edge S7) the ArCamera is always at 0,0,0. The rotations seem to work okay, but position in unchanged.
What's going on? I need some pretty urgent help or advice.
I have tried all the World Center modes but nothing seems to make any difference.
