Bad Performance on Mobile Devices

Hello everyone, I am developing a mobile game with UE4. But the FPS is very low (15 or 20), I tried the research I have done so far, but I could not solve the low FPS.

Here’s what I’ve tried:

  • Mobile HDR disabled
  • No Shadow
  • Only 1 static lighting
  • 512x512 texture sizes
  • LOD

I also have music and a HUD in my game, could this be causing fps drops?

Also my game stats:
