I had bought a Samsung galaxy s2 in the month of January 2012. After 3 days there were issues in the phone it use to hang regularly, camera error and voice echo, the phone was replaced as it was only 3 days old, but the replaced phone also had the same issue , after number of visits to the service centrethe phone still had the same issue, have sent couple of mails to the company but have not received any feedback from them, i want the company to payback my money as I have serious doubts in quality check department cause both the phones cannot have the same issue, and I have not bought the phone to visit the service centre again and again
