sir, i had bought nokia x2-02 from mobile store, dehradun on 12 june 2012. from the first day i bought there was some problem with the display(some line shakes for 1-2 sec). i thought it was due to my memory card or there is some software problem but on 25 june 2012 the display become completely black. i had gone to nokia care dehradun and they checked it. after checking they told me that your usb port of your mobile is broken from inside and your set is now out of warranty. it will cost rs 3000 to repair and cost of set is 3500rs. but neither my cell has fallen nor any liquid had gone in to my cell. that's not my fault i told them how can i break my port from inside but they are nor beleiving me. after that i had gone to the shop from where i bought my handset but he is also not taking the responsiblity. so tell me where should i go it's only 15 day i bought my handset.
