Question about DJI OM 4 - Osmo Mobile 4 smartphone gimbal

I use the iPhone 12 with the Apple Silicon Case. It works, but it's not super-stable, the clip is a bit too small (or the edge, which is about 1 mm higher, is a bit too high for the clip). If you run with it a lot, I would recommend an additional case and fix the magnetic-adhesive thing there. That should hold.

The clip does not work well with the iPhone 12 models because the clip is made for rounded smartphones. However, the iPhone 12 models have square edges.

I can't say. I iPhone XR.
