No adjustment needed so far. I also have a large USB battery handing from it in a carpenter pouch, so that’s probably helping keep it stable.
For phone control, it’s good to within around 75 feet of range in my experience. But once it’s recording, I never mess with it until the end of the game. I install it, align the camera, then walk away. Once the anthem ends, I hit record. If I’m near it, I’ll check every other inning or so to see if it’s still recording, but that’s it.
