One possible cause of the black screen with a blue LED light is a software glitch or conflict. This can happen when there are too many apps running simultaneously or when a certain app crashes during a reboot. To troubleshoot this, you can try booting your device into Safe Mode. In Safe Mode, only the essential apps and services will run, which can help determine if a specific app is causing the problem. If your device boots up successfully in Safe Mode, you can then uninstall any recently installed apps or clear the cache for problematic apps.

Another potential cause of the black screen issue is a hardware problem, such as a faulty display or battery. To determine if this is the case, you can perform a few hardware-related troubleshooting steps. First, try charging your device for at least 30 minutes to ensure it has enough power. If the blue LED light turns on and the device vibrates, but the screen remains black, it could indicate a hardware problem. In this case, you may need to contact Samsung or visit a certified technician for further assistance.

In conclusion, encountering a black screen with a blue LED light during a reboot on your Samsung Galaxy S7 Edge can be frustrating, but there are steps you can take to resolve the issue. By troubleshooting software-related problems and performing some basic hardware checks, you can hopefully get your device back to its normal functioning.
