my Samsung mini shuts down whenever I try to use it. I had a problem like this last year and I was told that my sim card was corrupted. Why has this happened again?
Good question, have you tried to diagnose? Does the sim work in a different phone, does the phone get very hot?
does it shut down when doing only one thing or when you call, text use the web.
