There has been a lot of complaints on this forum about the volume on the DInc2 not being loud enough in many sitituations. That is the one and only thing I miss about my Fascinate, the speaker was LOUD and clear.
Well I did a little digging around and found Volume+ | AndroidAudioHacks and also heard about it on All About Android and I am really happy with the results. After a little tweaking I was able to get some pretty respectable sound out of the DInc2 speaker. Just a word of warning! Be Careful and don't crank up the setting all the way or you could damage the speaker.
P.S. this app doesn't require root but there are other features that open up if you have rooted it.
