Question about FeiYu Tech SPG 2

When filming with fast pans, the video recording is quite jerky, there are always small "hangs" in it. Tested with various smartphones (Honor, Samsung, HTC) and Android 9+10. The same everywhere. Do you need 60FPS for smoother panning? The app only offers 720/30, 1080/30 and 4K/30, but my Honor 10 can do 60FPS in principle. Software from the Play Store "Feiyu ON v3.0".
