I have vattery drain and slow charge problem build 2019.01.09. I dont have this problem 2019.01.08 rom. And… Can we change notification and ring volume tone with volume up and down buttons? Can we just change the settings>sound. Only the media volume changes from quick sound settings. 2019.09 build
