i have purchased a HTC desire v phone just few months back on 16t jan 2013 from Mobile store dehradun (rajpur road branch), after using few months it started hanging and flash light does not switched off until battery is removed from hand set. I just complaint at service centre and they sent my phone to workshop (gurgaon). it took almost a month to repair it and i got my phone back after 25 days. again after using 2 or 3 days it started hanging much more than earlier, all applications took atleast a minute to open and further all pictures, photos and music files could not be supported by phone, it can not access memory card also, flash light also getting problem, it often gets switched on and not be off until battery is removed.
