It's OK When listening to google ( my library or their station), it does work all the time. It's says it's on, but won't take effect until you turn it off then back on.
No presets, pay up Horrible sliders, only need to fix the Android low volume too loud bug/feature. Would have paid a buck, now too annoyed. Tried it again now and the sliders reset all the time. Bought something else.
Doesn't work Tried to use this to reduce the volume below the android lowest level. App didn't change the volume at all, has a ton of ads, and still requires use of the "options" button which Google has been getting rid of. Worthless app.
Mainly installed to dampen for overly loud Bluetooth headphones. Works like a charm.
Freaks my mind It sucks me a lot does'nt work
One suggestion 1. It would be great if you add feature to turn it on off via notification bar. Why PRO VERSION IS 1.0.7 (Aug 2013) and this free 1.2.2 (Dec 2015) ?
Bug fix. If the new update fails, try to uninstall it first.
