I bought my Galaxy Flip 6 2 weeks ago and started using it about 10 days ago. Bought from a Samsung dealer in Dubai International Airport. 

In that time, 2 bright lines of light along the hinges have appeared at the left end of the main screen and are extending with time to the right.

This looks like a massive fault to me. 

The phone is in a genuine Samsung case and hasn't been dropped or badly handled at all. I was quietly proud of this really cool phone until this issue cropped up. 

Is this normal? I haven't seen this in any pictures pictures of the Flip 6, nor any posts about this.
