Hi, I have found this problem when testing last RiftCat 2.1.4 beta in NOLO Wireless mode.
I have hands with both controllers in front of me with constant distance between controllers. Then I start rotaing with all body to the right and left. When the outside conroller reach cca 80° of rotation, then its path change direction to back. See my recorded video
Then I have confirmned the same problem is in mobile application Alien Attack installed from NOLO Home. I have repeated the same test with only one controller connected and the result was the same.
Then I connected NOLO headset marker via USB to PC and made the same test in Visualizer and here was all OK.
This is why the problem is in the Android SDK.
Can anyone else please confirm this behavior in the Android SDK?
