Your phone is an n73? Format the phone.

To format

1. turn phone off.
2. hold the following keys WHILE its turning back on: (3 + * + green call key)
3. do not let go until it asks you about your location

Your phone will gain 44mb back and go back to normal. Phone will respond a lot faster too, as if it were new. Viruses would be deleted as well as other junk stuffed inside.

Important reminder:

If you have anything stored on the phone memory that you woudn't want to delete, such as pictures, videos, or whatever, back it up to your memory card or computer. The format process deletes all stored memory on the phone, but not the memory card.

my n73 hand set problem is if i connect the charger on the screen displayed not charging, and i use to charge the battery charger to store power in battery. charger is working fine but hand set troubled me and the other problem is if i listen the music files after 2 minutes phone is off, in a day its happening lot of times give a complete repairing solutions.

in standby mode press *#7370# n it asks resote factory setting press yes n it asks lock code just enter your lock code it will restarted n it'll be ok

What do you mean by 'open line' and 'open' if you mean switch on, the button is on top of the phone????????
