I need help on how to fix my phone. A long time ago my Samsung note 9 got cracked on the middle of the phone’s height, on the very right side. Soon, a black blob began to form around the crack, and over time increase in its size. A bit later, my phone screen had cracks all over, but not as severe as the one on the right. The black blob was the only problem but recently, as I was watching yt, the bottom half of my screen began to flicker with green/white, horizontal lines. Over time, the bottom half is filled with the green/white lines and it makes it very hard for me to use my phone since I cant really see through it. Sometimes it fixes on its own and only the black blob remains *which still is slowly spreading*. But now, that’s a very rare occurrence and the top half has become very dark while the bottom half is still green/white. When i change the brightness to all the way low, the whole screen turns black, when I turn the brightness all the way up, the screen turns black. I have no clue what to do. I turned safe mode on, held vol down/power button, turned developer options on but nothing worked. I don’t know if it’s a software problem because it never flickered for many months while after the crack, or a hardware problem.
