Soft Reset : Press Power + Volume(down) keys until the phone vibrates (about 8-10 seconds). Phone will reboot. This will not erase any data from the phone...
BTW, when you enable Auto time update .. even after a couple of minutes the time doesn't get corrected ? Your Operator should support this feature though ..
What you have just done is a reboot. The time will reset itself after a reboot, however, it should set to the correct time automatically if you have auto time update enabled and if your operator supports this function. Bes to check with your operator to see if they support this first before trying anything else.
I have sent the phone to care centre. After the centre has reserviced the phone, they said date and time have to be manually set. After a soft reboot, the date and time will automatically set to the default. So, I guess they are telling me this phone is like this. Thus, even if I enabled or disenabled, it is still manually set up. Oh well, this phone...
In any case, thanks for all your help.
