Unity 5.4.03f loading scenes takes for ever to load on Android device

I have ported 5 games that worked on IOS iPhone5 flawlessly. First two games had no issue with scene loading speed. However 3rd and 4th game have huge delay in loading scenes!!
I would wait for no less than 60 seconds for scenes to load in the 3rd game, but the menu scene loads just fine. 4th game is a disaster, it takes more than 60 seconds to load the menu scene, which is right after the splash scene!

i have tried to look up the problem, but don’t seem to find what exactly is causing this!
Removed light mapping, or with light mapping, no difference.
Tried to remove one thing that’s common between those two games, which was the bird flock which i got from the Asset Store, it also had no effect.

I am using a Galaxy note 3, which is equivalent to iPhone5, if not faster sometimes.
So really, i don’t see why it’s taking so long.

It’s driving me crazy, specially that i have disabled so many things, to try and find what is causing this. But no use.

found the problem, building for Android doesn’t compress textures as it should. So i had to go in and scale down all textures in the project. Now scenes load just find.
