Hi,
I made some mobilejournalism videos from arthquake in Italy this week and I have problems with jittering.
Even when Im not moving the Gimbal.
Never had it before. The lavier mic with trr connector is very light.
Using Filmic PRo without IS function.  
Iphone SE  +  rode smartLav+ mic  attached on it.



from 00:07 - 00:15 im not moving the osmo but you see the jitter.




another one with lots of jitter. Attached the Osmo mobile to a monopod in some images.from 00:43 you see it while im sidewalking...

I experience the exact same issue with the iPhone SE and DJI Osmo Mobile.

Since iPhone SE doesn't have OIS. I think it's just the vibration on the z-axis, there's really not much you can do about it, except walking more carefully. Another method you can try is to use flashlight mode and it should make it much more stabilized.

I mainly use flashlight mode when walking. But it jitters also when not moving..
