I have Had a Samsung Galaxy S6 For About 2 Weeks now, And i was just plugging my phone in when the screen went black and green lines started jumping around. Then my phone turned back on and a blue-purple patch appeared on the top left side of the screen. the touch screen didnt work below the patch but above it, it did. i attempted to power off using power off + volume down but no luck. i also knew it was working on the inside as the green light was flashing (btw what does the flashing green light mean?) and when i tried my fingerprint it vibrated. please help!
