Hi I upgraded to Nokia 5800 (touch screen) two months ago, now i kept loosing the signal (my other phone is on full bar) even in the good area, and the battery doesn't last for 12 hours, is there something i can do, set up or configuration to improve this?
Please help.
you need to upgrade the firmware on the phone of take it to a phone shop and get then to flash it then you will have the latest software and it should be fine.
