I have tracking issue with model tracking and galaxy s6. The tracking seems good at first but when we move the smartphone. It look like it's not tracking the object but some thing else. Here is a video with the problem. Does someone have a solution for this problem?
I have the same problem with galaxy s8 and it work on my axon7.
I'm using Unity 2017.3.1p3 and the model was generated with Model Target Generator Version 7.0.43
