Wow. It didn't screen cap what I saw on my phone. That's weird
Were you meaning the white lines you were sniffing from your phone? LOL just kidding.
Try taking a picture of the screen from another phone if the screenshot isn't capturing the issue.
It was a white vertical line going down at one point during my battery reading. I was also wondering if it meant I had turned my phone off. And no I am straightedge thank you
Welp, post back if you experience it again and try to snap it with another camera if possible. I haven't encountered that on my S6.
Yes it signifies when the phone was restarted or powered down
