Description : I already have several Nokia 3510 mobile phones, because I got used to it and it suits me. Suddenly everything is displayed negatively on the screen and I did not figure out how to change the display. Again, it doesn't matter so much, but it bores me in the head. Would there be an idea?
Last Answer : The mobile phone is OK again, just turn it off and on again. I didn't figure it out, I did a friend.
