Hello, I asked this question before but wasn't able to answer the reply. Don't know how. I have a new galaxy 9 and it just updated for the first time - new operating system - pie. A lot of things are good but I can no longer tell if my phone is on mute or not because the icon is green on a blue background on the quick notifications that you drop down. I have changed the background to many different pics and none of them changed these icons, I also changed the icons separately and had no luck with the quick drop downs. Please also tell me how to answer future questions/reply.
