Hi, i bought nokia N85 for about 4 months ago and here is the problem. Mobile worked just fine for 4 months, but recently when i was recording video and when i tried to look at it , nothing happened. Only what it was shown to me was 3 seconds of black screen, but there was audio. Ofter 3 seconds the time just freezes. So for example: video is 60 seconds long. When i press "play" the realplayer turns on and show just black screen for 3 seconds and then it freezes, but audio is still playing just fine.What should i do?
