My note 1 is good, the screen is just flickering. The note 4 has a battery problem that when I am using the phone for normal things, it just turns off. Other than that it is fine. I gave my note 5 to my uncle and when he gave it back, the menu buttons light up, but the screen is completely black. My note 8 is completely fine without issues except that the power button cover and bixby button cover is gone. i put a toothpick and hot glue to fix it. And sorry for late reply.
