[Fiftyshadesof Watts]

my s3 mini is rooted and I was planning on using music equaliser - custom to change the sound on the headphones but whenever I touch any of the sliders the screen goes back to the equaliser page so I am unable to asjust any of the custom sliders.
I have tried settings-more-app manager-all and cleared data but this didn't fix the issue.

I installed rocket player pro but some of my mp3's wont play as it don't like the format wtf its an mp3 the default player plays it.
I want a 10 band equalizer and reliable easy to use mp3 player any help appreciated thanks in advance
