My phone has a crack on right side corner in middle of screen. When I press the power button it has a white flash at the lower screen or some times it shows my display at the top half of the screen with the top right corner in black and white at the bottom. Can someone please help. I need to know what’s wrong and how to fix this.
Your phone has an OLED panel, and what happens from time to time when you crack the screen, you also damage the OLED panel. You’ll need to get your screen replaced to fix the issue.
