the trackball doesnt navigate very well. the onscreen movement freezes at times even though i am moving ball. also, the select button on trackball is not working. Also, some of the letters/numbers do not work. for example, when i press the zero, "yi" is typed on screen. help please.
no. ive pulled the battery out a bunch of times. it didnt get wet. is it possible that the keypad needs to be cleaned on the inside? or is it possible that the electronics inside the keypad pressure device are just toasted?
