Some of them yes but the main reason why i rooted my SGS3 was to increase the volume, now its insanely loud at full pelt. Also i rooted to play a few games that wouldnt work on the SGS3.
I havent delved into custom roms and such, i like my SGS3 the way it is, a few hacks installed and im pretty happy. Im now waiting on the official JB update to come through.
how did you achieve the volume boost?
