I recently bought a used Galaxy S. I really like the phone and I read somewhere prior to buying it that it has a decent audio chip so I was pretty happy. I wasn't getting the phone mainly for listening to music but I still considered it important. I installed the latest Cyanogenmod (not sure if this is unrelated but after googling I didn't notice people complaining so I don't think it is) and when I got to listening music I enjoyed the quality but I was disappointed in the volume. It's not terribly quiet, I just wish it could go 2 or 3 notches higher when you felt like listening to some loud music.
I'm aware of the option of buying a Fiio e3, but I don't like the idea of having to replace a battery every 20 hours of play time and having to carry it around.
Are there any other alternatives? Thanks!
