Ive been running liberty 1.5 for a few weeks now and ive noticed only one problem. The screen frequently wont turn on after its been locked. I can press all the buttons i want as much as i want but no response. I dont know if the phone actually turns off, or if the screen just wont respond. Ive got it to turn on maybe once or twice but its taken quite a while. I usually am forced to remove the battery and restart. Does anyone know if this is a normal problem or can it be fixed?
