Well i really only use 2 of the either or is perfectly fine
1. Mt settings (free version in the market is fine) has various different toggles and if you long press the ringer toggle you get a volume control
2. widgetsoid is one of my favorite ones they have soo many toggles, shortcuts ect and the have a dedicated one for volume control
they are both free and defenitly worth a try hope you find what your looking for
Last week I started using Suppressor Pro. I got it because I wanted to be able to create different volume settings. This way I have a profile for how loud I want things to be when I'm home and how loud when I'm not. This works instead of adjusting everything individually. I just select which profile I want and go.
OK heres the simplist way to take care of those tweaks we all search for.
go to market .. DownLoad .... "Galaxy Tuner"
it is for the samsung Galaxy Class Phones.. and it works.. a few Tweaks and Mainly One For Volumn.. qucik n easy ..
Hey
Since I got my phone I'm using this Voice controller app called Smart Volume Control . It's actually working pretty impressive.So I recommend it to you As my opinion
Here is the Play Store link
I've been using Smart volume control+ for a while now and I'm happy with it. I needed to control the volume on my phone based on my calendar events and SVC does that among other options.
I second smart volume control, been using it for a couple months now and it really works wonders for what you want. The options are endless, being able to have a ton of profiles and schedules for your volumes is a very cool touch. Start with the lite version first to play with it more.
For me I have used a few different ones, I used to use persist + for volume control, it worked well, but I too moved on to smart volume control + because of the extra bits of options it had. I liked silencing certain contacts the best for a certain time.
