Texture become dirty on Android

I am new to Android Development. I have developed a very simple game for android, but the problem is that, in editor everything looks fine but after building it for android, textures become dirty and distorted. I have tried many things but nothing solved this issue. Please help. Thanks.

In android device

Background import settings

Try using a legacy/mobile shader and see if the problem persists. I have this issue aswell with the Standard shader and it’s really annoying.
