I have been using this phone since last six months and I am personally feel that this phone has worst sound quality.
I think the speakers used in this phone are of low quality thats why it produce some bad noise which I didnt like at the time of hearing the music and watching movies also when I do not use earphones.
Second thing which I was expecting with this phone is protection of display. Here no such type of protection is given in this phone. So they should have given some protection for this such as Gorilla Glass.
