So what I wanted to do was change the lg default background during a phone call to the android stock gradient as i prefer the look of it better. I extracted the phone.apk out of the /system/app directory and found that the gradiant images are already there. so my question is, why is the phone not using these images and how do i change it so it does. My first thought was a metamorph theme that only changed the phone app but seeing as the images are already there i guess theres no point.
