I have an Android S6 Edge. Screen is black and a blueecond. How do I fix that?

[AC Question]

Screen is black with a blue light flashing every 5 seconds? I plugged it in but no difference. Worked fine last night.

Welcome to Android Central! Pull the battery for 10 seconds, then reinsert it and try to power on again. You might have to press and hold Power for 10-15 seconds.
