Hello,
I bought a Nokia C6-00 yesterday and charged it 3 hours as the cellular shop said. It worked for the first 5 minutes at it automatically turned off. This happened several times and I went to the cellular shop to exchange the phone. They gave me an another Nokia C6-00. I charged it again and the same thing happened.

I heard that their is an auto turn off sensor and it automatically turn of the phone when your face get too close to the phone or something like that. Does anyone know how to turn it off?

I also heard that this might be a sim or memory card problem. I removed the memory card & sim card (replaced with an another) and they didn't work. This Nokia is a such a pain

Does anyone know ze answer to this question?
Thanks!
