This Alcatel Idol 4S Windows 10 Phone's Maps app used to have nice, loud navigation when I was driving. Suddenly it's pretty quiet and hard to hear what with the traffic noise on city streets. I can't find a way to make it louder. In the app's settings it has 3 settings, quieter, normal and louder. Louder is nowhere near loud enough. Why is it so much quieter than it used to be and how an I make it loud again? Thanks for help!
