I just got a blackberry tour . I got it from ebay cause my other one got stolen. Didn't know if it was the brightest idea . I noticed the battery life isn't very long. But I also noticed that it just shuts off randomly. If I ever get a text message or any message , sometimes the screen stays black and it turns off . Or with a slight impact the phone shuts off. I don't know if it is the battery or it is the phone. I also have a other problem. Sometimes when the phone shuts off when it is full battery it turns back on , on low battery , I have to take the battery out and put it back in and then it'll work properly. I'm just scared to do it one too many times to screw up my phone.
