I'm running the Android beta with the Wiim Amp so I don't know if this is a universal issue. But I think it would be good to be able to adjust the volume (using the phone's volume rocker) while in the EQ settings. If I'm tinkering with something, I have to back out of that page to adjust volume. Not sure if this is a bug or intentional, but I think it would be super helpful to change this behavior!
