How can I get shaders to render on Android?

kitfox It also seems weird that the Framebuffer Allocation.mobile is greyed out in my editor. Does that indicate something?

It's the same for me, think it's just meant to indicate that it's secondary/not relevant to the platform you are running the editor on. Like it only applies to mobile platforms you would export to. But I'm just speculating on that.

edit: btw, I assumed you already have read it in the docs (since it's the top result on google when making a search for it), but should have asked before if you had:

When using GLES2, some custom shaders may break when exporting to Android. This is caused by a lower shader precision being used by default to improve performance. You can force high precision on all shader computations by enabling rendering/gles2/compatibility/enable_high_float.Android project setting, but this has a significant performance cost and won't work on all devices.

I meant other godot 3 versions, sorry. Should have been more specific. I was thinking along the lines, perhaps there's some bug at play that might have been introduced in the version you are using. And if not using the latest, perhaps it's been fixed in a later one.

Claims OpenGL ES 3.0 and 3.2 support, I see no mention of 2.0 tho I have a hard time believing it doesn't support it. On the other hand, chipset announcement date is 2014, who knows how well they still support it with drivers...then again, gsm arena clearly indicates it's a 12nm chip, so probably just the gpu arch is ported over from the original 20nm hopefully it is still supported then too.

BTW, gsmarena.com and notebookcheck.net are great for finding out hw specs of phones(and laptops also for the latter). Def. recommend bookmarking them.
