Recently after exporting to Android, the shaders that used to work on Image components stopped working. Everything looks perfectly fine in the Editor but when tested on an Android device, all images with stencil shaders would disappear. One time, it managed to work like before on a Xiaomi Redmi note 4 but not on an Oppo Reno, both phones did not show any error on Android Monitor, no compile error either. Feels a lot like a bug.
I tried deleting the shader cache in the project library folder, re-importing all the assets, reinstalled Unity, used OpenGLES2 only on Player Settings. Nothing works.
Any ideas?
My shaders:
// Upgrade NOTE: replaced 'mul(UNITY_MATRIX_MVP,*)' with 'UnityObjectToClipPos(*)'
Shader "Particles/Multiply (Double)" {
Properties {
_MainTex ("Particle Texture", 2D) = "white" {}
_InvFade ("Soft Particles Factor", Range(0.01,3.0)) = 1.0
// required for UI.Mask
_StencilComp ("Stencil Comparison", Float) = 8
_Stencil ("Stencil ID", Float) = 0
_StencilOp ("Stencil Operation", Float) = 0
_StencilWriteMask ("Stencil Write Mask", Float) = 255
_StencilReadMask ("Stencil Read Mask", Float) = 255
_ColorMask ("Color Mask", Float) = 15
}

Solved, the problem might be caused by Unity not detecting the #endif tags.
