Profiling Android Unity 2D frame rate with parallax layers and particle effects.

[RichardPL]

I'm developing a 2D pixel art platformer in Unity, and while the game runs smoothly on my development PC, I'm getting inconsistent and sometimes choppy frame rates when testing builds on mid-range Android devices, especially in levels with multiple parallax layers and particle effects. I've done basic optimization like sprite atlasing, but I need a more systematic approach to frame rate optimization. For mobile game developers, what profiling tools and strategies do you use to identify the specific bottlenecks on target devices, and what are the most effective ways to cull off-screen objects or manage draw calls in a 2D context without sacrificing the visual density that defines my game's style?
