when trying to activate my bluetooth...i get the bluetooth settings window...bluetooth on.....visible...and my device name...and SAVE....then nothing happens !!! try to look for devices...press NEW and also nothing happened

this problem 1st occured when i tried to connect to windows just to send a few music files....the bluetooth was turned on normally..and during the transfer it disconnected and whenever i try to activate it the same thing happens to me....other devices would find my phone as if it was still ON...but couldnt attempt to connect to it

i tried rebooting the phone..restoring settings...and it was fixed !!!

did a couple of transfers with other nokia phones...that went on ok...

then on another occasion i was trying to activate it ....and the same thing happened allover again !!!!
tried to do what i did last time...restoring settings and so on...but till now it's not fixed :

any clues on what i should do...or has anyone experienced the same problem ???

is that a software issue or a hardware issue( i feel like the software is dissociated from the bluetooth device itself am i right ??? )
