I have had my LG Cosmos VN250 for less than a year and recently it has been powering off for no reason. Sometimes when I go to answer a phone call or slide the phone open to use the keyboard it will shut off and then power itself back on. Other times it will turn off when I am not using it and won't power back on and I won't realize it until I go to use it so I never know how long it has been shut off. It is very frustrating especially because when it does it when I am receiving a phone call it doesn't record who the call was from in my received calls menu, so if I don't get a chance to see who is calling before it shuts off and then on, I have no way of knowing who called. Has anyone else experienced this problem and is there any way to fix it?
