Nokia 6600 call log problem

Hello Friend,
I know Nokia 6600 is not a very common mobile phone these days but still reasonabale peoples use this phone. This is because the phone has its own pluses and the best thing is that it has symbian operating system which has some very good features. The main problem faced by Nokia 6600 users is call log problem. When you call a number or receive a call from another number, the call log option doesn't show recently dialed or received numbers. It updates the information only when the user restart the phone. This is a common problem and normally peoples don't know the solution and are living with the problem.
Friend, You can solve this problem by method provided below : -
> Back up all your contacts and data saved on your phones memory and also on MMC card.
> If you are unable to back up, take your phone to authorized service center.
> If you have made the back up, charge your phone to maximum level and remove the charger.
