SGH-J800 in month of April from Raja Telecom shop. 120 Ashiana Har Nivas, Dak Bunglow Road, Patna -1 in Rs.-6900/-.I got 1 year guarantee/warrantee. On 25.07.09 I suddenly found that display screen of my mobile turns white. I send it to patna by my staff. Where my friend has complained in service center in patna on dated 03.08.09 vide work order no. IMHP/03-2. After repairing the said mobile was returned on 14.08.09. After 4 days I received my mobile through my staff. Mobile works one hour properly after that it again turn while facing the same problem. I became irritate to see this. I also found a black miled spot on display screen with a pin size displaying light. I suffered much mental tension. I request you to look in to the matter personally and change the mobile immediately.
