How to prevent graphicsSettings.json from reseting?

Than the EA team should add kinda graphics settings(or at least a seperate tool for them). Otherwise I know htat the phone I use is capable of a lot more(I had decent framerates in Real Racing 3 where a lot of cars in scene, very high quality fresnel, HD textures and real time reflections. And it is one of EA games) than the game shows now. There is no anisotropic filtering, textures are pretty small resolution, reflections are too constant(they could at least switch when entering tunnel if not being real-time rendered). There are no specular reflections on road from rain. And the phone can handle much more... Please, give use a way to customize game appearance(I see there a lot of options in gameSettings.json, what a nice sandbox, but game just resets it. What a shame)... 😞
