Had one since launch, first foldable. Zero issues with the interior screen/crease. People need to remember you’ll hear about the issues, you won’t hear about people just enjoying their device normally.
I disagree with people who say the inside screen is useless. For one, I use it to share pics with family because it’s easier for multiple people to view. I also use it for watching videos, it’s quite nice.
I am also a remote sys admin. I use the inside screen for RDP/ssh sessions to remote machines for quick weekend maintenance. I will never go back.
