I've had my Note 3 for a little over a week now, and I'm worried it may have a defect. Occasionally, I get a bright green line that runs the entire height of the screen on the far left side. It runs through whatever else is on the screen. I don't know what triggers it, and I can't make it happen. It's only happened maybe 5 or 6 times, but I'm worried I have a problem screen. Any advice on what I should do?
