Samsung Galaxy S2 — Faulty Mobile

Address:

Pune, Maharashtra

I have recently purchased galaxy s2 on 15 august 2012 for 26,500 INR. I am not satisfied with its performance the battery gets heated up during charging or when i use my web applications or i download something.The battery takes 4-5hours of charging time,even if i keep it switched off and then charge.The application such as messaging,web browser,games gets crashed and hangs for a minute or so and the battery drains outs very quickly and i have to charge it twice a day....the main problem is in music player when i connect my headphones the sound gets distorted and awfully irritating and i am just hating it....and they say the gorilla glass is scratch proof but it is not so......i already have some scratches on it.......samsung.....what the heck!!!!!!!! my IMEI is [protected]..........WHAT SHOULD I DO...
