Another problem is using BT. I can't BT direct to my phone but must use Ovisuite..otherwise can't sync. 

I had this problem since v 11 and been posting a lot bout it. Guess nobody reads it 
I rmb teaching how to solve this prob.

Do you have fm transmitter as widget in homescreen? (most of the time the cause is this and you just need to remove it)
If not then remove all widget from home screen then off phone for 5minutes.
Then start back it'll be ok already

PS: when you start the phone do not touch it and just let it lock by itself. Else it'll trip something and the light won't off again when you lock
