Samsung phone users occasionally face the frustrating issue of their devices flashing but not turning on. This problem can stem from various reasons, including software glitches, hardware failures, or battery issues. This article aims to look into the possible causes and solutions for this problem.
Understanding the Flashing
When a Samsung phone flashes without turning on, it may display a logo, a series of lights, or even a blank screen. This can indicate that the device is stuck in a boot loop, which means it is unable to complete the startup process. Alternatively, it could be a sign of a deeper hardware issue that requires professional intervention.
