P3452 auto dial last number when wake up

[bebobebo]

I have P3452 (Elfin), A weird problem is happening to me. The phone goes from sleep mode to automatically dial the last received/dialed number as soon I press the open button. I tried reboot for the phone but still doing the same.

I have a lot of sotware on the phone and i don't want to loose it or reisnatll it.

Any ideas about how to solve that problem
