Could you please diagnose my bottleneck?

Thanks for your reply, but I think the main problem is very simple: my device is slow. My phone is LG Vu 3, which uses the same CPU/GPU with Nexus 5, but the firmware bug seems to be not my case. My game is KHBbS, which runs at decent speed in many scenes but slows down dramatically if there are effects, like splashing water, on the screen.
I believe the real solution is buying a better PC.
