Phantom 4 ADV - latest firmware & DJI GO 4 app (iOS).

In any of the exposure control modes with stills the aperture does not change (visual inspection) - e.g. using aperture priority where I first noticed it.

In video you can see the aperture changing OK - or in MANUAL mode with stills.

Any ideas?

Could you upload some original images from the SD card to the Dropbox, then provide me with a link to download them? Besides, what mobile device are you using? Is the APP update?

OK so it seems to be working when the still is actually taken but not on the preview (which DOES work in video mode).
