I used to own a BlackBerry 10 phone running BB10 OS. At the time, the dev team accepted suggestions on how to make the OS better, and I suggested they make the volume controls logarithmic instead of linear, and they did! I loved how quiet that phone would go while still remaining clear—I used to listen to audiobooks as I fell asleep at night, and rather than use headphones I would just set the volume to level 1 or 2 and put it on my pillow beside my ear. I haven't been able to do that with any other phone since because the volume doesn't go low enough, or if it does the audio is muddy.
