Vuforia Not Working on iPhone8+

By dpizzle on Thu, 10/12/2017 - 23:32
Vuforia SDK Version: 6.5.22 - Description with steps to reproduce: Unity version 2017.2.0f3 Something is clearly not working right on the iPhone 8+ and image targets. They appear noticeably jittery compared to an iPhone 6s+. The video below clearly shows it. This is very noticeable and easily reproducible. I would expect an iPhone 8 to at least compare with the tracking quality of a 6s if not exceed it. I've restarted the app to see if maybe a profile needed downloading or something. I've also tried speed and quality settings with no difference. If the iPhone 8 is not officially supported yet, please let us know, I didn't see anything in the release notes. http://relativedistance.com/VuforiaTest.mp4 - Development OS (Mac OS X, Windows, Linux): 10.12.6 - Mobile OS and Version: 11.0.3 - Mobile Device Manufacturer and Model name: iPhone 8+ - Do the Vuforia Sample Applications show the same behavior?: I didnt bother cause this was literally just an ARcamera, Image Target and Cube, no other scripts or assets.

Did some more testing.  The discrepancy between the two devices tracking quality also exists in Unity 5.6/ Vuforia 6.2.10.

After more research, my gut says:

This is also present on the iPhone 7+ given the camera similarities

and

It has something to do with Optical Image Stabilization (OIS), Focus Pixels,  or Cinematic Video Stabilization

Thank you so much,  here's some steps to reproduce if it helps.  It's easiest to see on the sample VuMarks, it's there on the sample Image targets, but harder to see (it's more prevalent on some custom image targets more than others, but I couldn't figure out why).

I missed this post, patch is working, Thanks!  Also checked 7.0.26 and it seems fixed out of the box, but it's a bit too buggy still to use.
