My Samsung Galaxy SGH-T989D phone turning off by itself while it is being charged. In some cases, I was charging the phone while driving and having a conversation, when the phone turned off... In other cases, I was charging the phone at home, just to find out that was already turned off by itself... It is not happening all the time, as in some cases it is working just fine. Any advise, please? Should I contact Koodo or Samsung in order to get this phone fixed (this phone is less than one year old)? Thanks.
