it should let you see what the lens is seeing in live time. is there a setting i need to adjust ? i just bought the phone used. it was working fine until i put a new chip in it. once i put the new chip in it it wouldnt turn the screen light on either unless i shut it half way and then it would flicker back on. until i would open all the way again. then the light would cut out again. like a wire was loose going into the ear section There is certainly a hardware problem - possibly an electrical fault in the phone. Please take it to the nearest Nokia Care Center at once! Delay can just result in damage to the phone.
Its better to get it fixed by Nokia itself. They may be expensive, but they are reliable. |
