Get nature shaders run on low end Android devices

Hey all,
I'm currently working on my first game for Android. I'm using trees from the Standart Assets enviroments package to bring my world to life.

The game works perfect on my OnePlus One, but when i try to play it on my lower-end Samsung Galaxy Tab 4 7.0 it seems like the nature leafs shaders aren't working.

Is there any way to include the shaders even on lower end devices? Or is it a completly different problem? Maybe alpha of the leaves? If so, why does it happen?
