My blackberry is about 3 years old now and it has been acting up badly lately. Ive had to clean the ball a few times by removing the entire casing. Lately I've been receiving the white screen of death often but today it was going crazy. I did the battery pull 5 times in a row before the white screen disappeared. Im not sure if I might have messed up a wire while doing the ball cleaning. The screen has also been glitching all day. Does anyone have any suggestions?
