Okay. Sorry to hear. I thought green line issue was resolved by Samsung, but they are playing with their users.Same issue occurred in apple iPhone as well. However, they resolved the issue in there next update.That's why I'm loosing trust on Samsung.

Have you updated the os

Omg, your shots are awesome.Help me to learn a lot of things.

I'm still on ui 5.1.1

It's better to don't upgrade the software
