Please help Just replaced my S7 screen myself, thought it would be easy peasy. It wasn´t. Now my S7 screen won´t stop flashing. I know the screen is working fine as the Samsung logo when turned on shows fine, as well as the screensaver when charging. Please help!!! I took a video so you can understand better what I´m talking about. Thanks a lot.

I would conjecture to say that the screen in not as fine as you might think. It may be flickering on boot, but it is not perceptible, because the boot screen is not as " visually intensive" as actually using the phone. I would check to verify that the cable is securely connected to the logic board and that both the cable and the motherboard are not damaged. Let me know what you find!
