I´ve got serious problems with my new C7. While using it, software freezes regularly und forces the phone to restart. As I´ve learned in another german forum, other C7-Users have that problem, too. I did reset the phone and update the firmware, with no effect. Others say, there might be a problem with the simcard-interface? My simcard is really new...
There is a problem with the phone. Take it back and get it replaced. I had the same problems but my second phone is perfect.
Read the other threads on this forum and you will see what I mean.
Mostly symbian Phones software crashes lot even though they devlope new varities of symbian.There may be issue in hardware to software interface.So get it replaced.I am also C7-00 user.
