Shader not showing in mobile build - unity3d

Question

So, I have found this glitch effect shader online which is working fine in the editor but when I'm building it for mobile it does not work it just shows the transparent image. I've added that shader below. I have searched online for answers and applied some of them (like always include shader in graphics settings and all that) but nothing worked.
Shader "Avi/Glitch"
