Re: Nokia C3 get switched off whenever it vibrates
I was having the same issue with my new nokia c5 which was started behaving the same as your nokia C3 is behaving. I think your phone to need software up gradation. As usual this type of problem mainly occurs due to the software only. So please contact to the nearest nokia care center. They will help you by upgrading your mobile software. And this way you will get the solution from this problem. Try doing this.
