It sounds like your charger is faulty, or your phones charger connection is faulty, try borrowing the same charger from a friend, if it does the same thing, your phones connection is faulty Regards

My Samsung SCH-u540 keeps turning on and then shutting off
Sounds like you have a defective battery. If you can use the phone normally with the charger plugged into it that is more than likely the problem. Step one is order a new battery. If that don't solve the problem take it into the store, but only if it's under warranty, otherwise shop for a new one.

I did not care for this answer yesterday when it was given to me. However, it has gotten to the point where you should speak to a Samsung representative. The phone # is 888-987-4357. He/she can probably help you on the phone but if you do have to go into a location, at least you will know

Good luck!

what you can do is do a hard reset of the phone press *2767*3855# this will reset the phone as if you just purchase it from the store...this should correct the issue
