[Android][GLES] Shader is not compling on Samsung S3 devices when application is ran on Adreno 225
To reproduce:
1. Open attached project "ShaderFail.2019.1.4f1.zip"
2. Build for Android on an eligible device
3. Observe the build on the device
result: shader is not compiled properly due to errors
Reproduced in: 2018.4.3f1 2019.1.9f1, 2019.2.0b8, 2019.3.0a4
Note1: 2018.4 build produces black screen, 2017.4 is unable to build the project due to errors
Note2: could not check on latest 2019.3 as ever since 2019.3.0a5, the minimum API level is 19
Note3: not reproducible on Vulkan (on devices that supports it)

Resolution Note (2019.3.X):
The shader in question fails to compile due to two issues:
- It uses unsigned integer maths that is not natively supported by OpenGL ES 2 GLSL
- It uses texture sampling functions with explicit derivatives, which require and extension on OpenGL ES 2 GLSL to work
Workaround for the first issue: don't use integer math. The shader can be easily converted to using floating-point calculations (e.g. 'float2 uv0 = float2(index.r % 4, index.r / 4) / 4.0;' -> 'float2 uv0 = float2(index.r - floor(index.r / 4.0) * 4.0, index.r / 4.0) / 4.0;').
There is no workaround for the second issue, the device in question doesn't support the required extension, so this behaviour is by design.
