is there a way to use pro mode or the default camera app on my s22 ultra, so that i can tweak the settings of my camera?

Hi there. Thank you for reaching out. Yes, you can use your original camera app when using the DJI OM 5. However, you cannot use the features in the DJI Mimo app (the original app that you need to use when using OM5) and the unit will only serve as a standard stabilizer. Hope this helps. Thank you for your valued support.

O i see.
