A shop UI with Scroll Rect runs very smoothly in Unity Playmode(140fps) and hangs a lot in android(8fps). Please see the description

Hello there,

I have a scene where I need to create around 20 GUI buttons for now to make a Augmented Reality shop and I am creating the buttons at runtime. The components in the scene are very basic and you can see them in the image attached below. The application in Unity play mode runs at 140 fps and when the same application on an android device runs at 8-10fps . And please mind that my computer is a very normal one with Pentium,4GB Ram and with Intel Graphic Card. The only part remaining is this Shop UI and I cannot get pass through it..Can anyone please help me..Thank you in advance link text

I have removed the Skybox and made changes in the Project Settings/Quality..
