I have pretty good lighting in the kitchen and there will still be a grainy background in the video. I'm using the samsung s8. But when I go out the quality is perfect. I feel like there's something wrong with my house, most of the lighting is terrible. Like my bedroom for example, the idiots who ever built this house put the light in the corner of my room. So the light does not spread well around my room. I bought two light sources even though that still doesn't do much. I really don't know what is wrong, and I guess my home is not the only place like that. Pretty much all the house where I live seem to be bad for lighting, wifi connection, air-conditioning, ugly carpet, and phone service connection. My mom says the house are cheaper that is why we moved, but now I'm realizing the reason it is cheaper is because of the quality of the home.
