Hi. In ROM Havoc and Syberia and Resurrection Remix, this feature is built right into advanced settings from the creators of the firmware. In /e / and lineageos of this No. I searched the Internet (how to change the volume pitch in Android) but all I found this Xposed + module volume step, but it didn't help. Recently tried Localized ROM MIUI Masik. It adds volume and decreases gradually, immediately, without a separate tab with the settings. So, in General, the situation is this: put your phone on the chair next to the bed and start a movie or show, add sound when viewing (default added 6-13-20-26 and on). 13 already loud, 6 silent. You need 8 or so. PLEASE can developers/ e / ROM change the normal (default) adopted Android volume control on smoother. to single press adding and subtracting sound by 3.(That would be in VLC, etc. the volume change (+ -) 3, in the settings you need to select 60.
