My cell phone was going crazy, not ringing, would not shut off, woman's voice replaced all functions, but the worst part was it just kept calling a long time friends number over and over. I took it to ATT&T where the tech told me it was a cheap phone so to just replace it. Did not know it had a replaceable battery but did come up with a solution---one round from my old H&R 10 gauge goose gun. Hasn't made an unwanted call since.
