[Android] Debug vs Release build FPS

Hi everyone,

UPDATE: I checked once again and it seems that the low FPS is due to the Maximum Allowed Timestep. I have no problem with the lowering/increasing it but I'd like to know why does the timestep affect my sliders in-game although I'm using co-routines instead of Update/Fixed Update -- Example: a slider that should last 3 seconds to reach the end, feels like each second lasts 1.5 - 2 seconds instead.

My question is: Why does my debug android build have much better FPS than my release build?

Details:

• Simple 2D, UI-only, incremental game

• Multiple optimizations already performed (multithread rendering, pixel perfect canvas turned off, quality set to Fastest and textures set to half res, physics timestep modified and script optimizations as well)

• Testing on Samsung Galaxy Camera (GC100)

• Using this for the in-game FPS counter: http://wiki.unity3d.com/index.php?title=FramesPerSecond

• Yesterday, I created a Debug build and checked on my device - the FPS was a rock-solid 50, with no spikes at all. After that I built the release version, without changing the project at all and uploaded it in the Google Play dev console.

• Today I downloaded the app from the Play Store to "officially" test it and it only has 18-20 FPS max.

Any tips on why this could be happening would be greatly appreciated.

Thanks in advance!
