Carboard broken on Samsung s6/s7 phones?

I’ve tried the suntemple demo in cardboard vr mode on an s6 and an s7 Edge…the gyro tracking is a jerky mess, my ipod touch is far smoother, is this a known problem?

edit the scene is buttery smooth in normal mode and unity cardboard scenes are smooth on the phone, it seems to be a ue4 cardboard issue.
