I just received the 7 plus tab for Christmas. In the few short days that I've owned it, it will work great and then the screen will not turn back on from 'sleep mode'. I hold down the power button and touch the screen to get it to turn back on. But, for $400, I am very frustrated that this is happening at all!!!!! The 'Live Chat' operator at Samsung told me to do a "hard reset" by holding down the power and volume button. Told me that doing a 'Factory Reset' from settings was not the same thing. And this would make the software more stable. Is this true?? I do not want to have to input all my information again. Shouldn't the device have been at the 'factory settings' two days ago when I first opened it? Looking for some advice.
