I am using this mobile yu yuphoria since when it launch on amazon.com. well I would say that I m fully satisfied with this mobile although it makes me some little malfunctioning but all over I find these are just minute problems when I compare it with others. just one thing is not good about this yuphoria phone and that is its music. So what I did, I downloaded audio jet mp3 application and adjusted its equalizer according to my listening needs. and brought another earphone headset piece which produce sound. Now its sound become amazingly better I can compare with any other company’s mobile. now sound experience is amazing
