Eureka. I finally realized just today that the Movi Cinema Robot clamp and the rounded corners of the Moment iPhone photo case don't mate as tightly and evenly as it should. It has been emphasized to me to make sure the iPhone is gripped properly on the Movi--- but I found it very easy for the Movi to hold the iPhone with Moment case securely but also at the same time slightly unevenly because the Moment case has some give to it. That soft rubber compound on the case means I can mount the phone and still be tilted by a degree when looking at the horizon. From now on, I will be jiggle and press down the clamps on the left side to make sure it is even. (A naked iPhone don't have the issue.) Troubleshooting this issue was tougher since it wasn't happening consistently because I may mount the phone "correctly" some of the time and I was blaming it on the MCR. (And it looked like it was secure in the clamps) Oh well---A big loud Homer Simpson "DOH"! ----Since the issue seems to be the Moment Case being a bit too fat for the Movi clamps and hence my "leaning" issue.
