Phone locks after call vie bluetooth
I have SE XPERIA ARC, with Android 2.3.4
Whenever I'm in the car connected to bluetooth, I disable screen auto-lock and screem timeout (with Tasker or Llama). The problem is that when I end a cal via bluetooth (actually, when the other party ends it), the phone locks up and I need to open it to continue use GPS or whatever is running there.
Anything can be done about it?
Thank you in advance.
