First I a new to the BB scene, So bare with me. I have 8330 with OS 4.5. I have had it for about 4 days now. I love the phone. But I noticed something. Before when I would Lock The Keys the phone would dimm down to completely no screen, Now it just dims a little and that is all. It doesn't completely shut off like it used to. Does anyone have and idea on what is wrong or what i did wrong.
