    I don't see how this version was released with such a huge problem. Beta testing?

    We are also having the exact same problem in 2017.2 on iPhone6+ and iPhone5.

    Same issue here in 2017.2.0 and 2017.2.0p4 on iPhone6+ / iOS11.x. Really glad I found this thread as it is almost not noticeable in my project and if it weren't for the fact that I have spent a year working on the project and building to the device I would have had a very hard time proving the existence of the problem to some associates.

    We have some sort of interpolation issue with Unity that has come up in 2017.2 see below:

    It appears to be the same issue as this, with physics interpolation hiccuping and stuttering. We have rolled back our versions of Unity to 2017.1.2 and are hoping this issue is fixed in a future Unity release.
