That setting changes the equalizer within Google Music. Im not sure it does anything else. I use Volume+ with great success and have never toggled that setting prior to reading your post.
I did confirm it works with Google Music's "MusicFX" setting.
You have to go into settings, sounds, after volume plus is installed, you will see n addition to what you are stating the Music FX option, u will then also see Volume + under Music FX, a new option is there for volume plus.
In place of Music FX select Volume Plus, this will activate Volume + .
Maybe I'm wrong but until i selected volume plus in under settings, sound, it didn't seem to make a difference. Even so.it makes a small.difference, the speaker only distorts.
I picked up Razr for my.wife, GNexus for myself yesterday, with the mid January return period figured I'd try the GNexus.
Copying files to the GNexus over MTP, if i don't copy.to the root of the GNexus storage area, file copies will hang, copy to the root.no problem. This is aggravating as i like to use the PC to move around files and folders on the phone but if doing anything other than copying to the root, even moving files around within the phone's storage it hangs. I read many examples of others having file.copy issues (slow, not reliable etc)
Seems some don't have file.copy.issues., def miss mass storage mode.
Lost 3g connectivity once already, in a non LTE area at the moment. The display with the same pics and wallpaper used on epic touch, on GNexus colors are dull, camera wasn't as bad as expected but not much better than my original Droid indoors. Probably will go.back but i can't use a gs2 on Verizon so i wanted this phone to meet or.exceed the gs2 so badly, 2 yrs to live with so many shortcomings is rough. Guess as much as hate too, waiting another few months after waiting all 2011 may be the answer. Unless the GNexus grows on me. Right now and all.day today I'm.using the epic.touch wifi only still, ha.
With the search bar at the top and virtual buttons, there's to me slightly less room.on the GNexus over the 4.5" ET4G, only when playing a YouTube video.full.screen is the GNexus slightly larger and then it's a small amount and the colors are washed out. I think anyone that says the GNexus blows away the gs2, at least the ET4G, they haven't used the epic touch much or at all as the camera, speaker, vibrant display (i will.take quality over resolution), etc - then ics will be avail and the new ToucWiz i dont mind, it actually makes for useful stuff like joining Facebook contacts, power widget with rotation and other items, this is.off topic I'm realizing, sorry, just frustrated.
Good luck to us all with getting the volume situation corrected, play a few YouTube videos for those that say they can't comment on the speaker.
