Samsung Replenish

This Samsung Replenish shuts off randomly when user is on a call and it says low battery when the battery is more than half way charged, the screen goes lock constantly without attempting to lock the phone. It overheats pretty easily. The internet service is terrible. The phone has a hard time picking up the 3G signal and it loses connection everywhere. Even when using a wi-fi signal this phone often disconnects from the internet causing frustration. I normally do not say this but this phone will not be worth a dime. Try to keep off it for it's own good!!
