Taking this back to the Apple Store, but thought I would share. I've had just about all the iPads going back to the original and have never had an issue. The 10.5 iPad in the picture is a replacement after the first one was replaced last week due to a dark bruise on the upper hand corner of the screen. And now the replacement iPad seen in the picture developed this think black line in the screen while I was using it, which does not go away no matter what I do. Did force restart, as well as restore - still there. Hopefully the third time is the charm.
