FrameRate droped after Unity 5.2

Hi,

I am working on an android application based on UI Canvas. Before the update (Unity 5.1) I had on my phone 60fps, and right after the update (Unity 5.2) I have 20-30fps.

On the Editor it runs ok, its a computer after all, but now my application is ruined due to this bad framerate…

What is going on with Unity 5.2?

Edit: The problem comes from the ScroolRect I have on the application… Performance Bug?

Edit:
Update!

I just upgrade Unity to 5.3. Framerate increased by 20-30%. Much better, bud not perfect.
