Mobile Reflection Problem

Hello there.
i have an annoying problem
While everything is normal in the editor, there is reflection in all objects on mobile devices.
i can't understand why this problem occurs.
In Editor (2020.3.24f1)



In Mobile (Device is Samsung Note 4 Exynos)



i tried these methods;

1. deleted the materials and created a new material and used mobile diffuse shader, still the same result.(also added/changed animated shaders but they were not active on mobile)
2. deleted the shader cache and it still didn't change.
3. deleted the whole library folder, still not resolved.

What could cause this problem? bug or not ?
color space is gamma
graphics is used by default settings

Okay. Are you using mobile shaders?

Also, do the materials you are using, have metallic, specular or mirror reflective options? If so, turn them off and see if that solves, the strange reflective problem you're experiencing.

 

i am using mobile shaders.(i wrote it in the tried methods)
problem is that when i build out on mobile, the shaders changing(auto) to the standard shader and the reflections are fully opened.(too strange)
