Lag after change scenes on Android

I’m making a pachinko game for Android, its works normally when I open a scene, but starts to lag when I change to another scene (due to over processing of Physics2D.FixedUpdate), but, as I said before, this problem only happens when I change scenes (even in the same scene I was before without lagging). Please help…

Use the profiler to track down where the issue is and work back from there.

I made this, as I said before, it is due Physics2D.FixedUpdate. But this only happens when I change scenes, even in a scene which wasn’t lagging before. I also tried to destroy all game objects before changing the scene… but this also doesn’t work…
