I have never seen that on my Android tablet (cheap Huawei)... With iOS you can turn it off... have you gone into the advanced settings on your preamp to see if it can be switched off? Also, are you running a MusicCast widget? If so, nuke it.
This industry is not getting cheaper and cheaper, we're simply convincing ourselves that we have to push the cheapest option to customers. #makesonosgreatagain
