Looks like rushing the product out the door to meet the launch date before it was really ready.It's called regression testing. And you're right, they can't test every scenario.
Review units were still super buggy and crashing days before release and they were releasing new drivers/firmware to fix major issues right at launch day.
This should have been sorted out earlier.
The latch release hardware/software should be a much smoother experience. Even when the latch release works properly, it looks very inelegant and rough around the edges in the way it pulls off.
That is not an example of testing "every scenario" Releasing the latch smoothly is basic.
When people start installing lots of strange software and trying to use odd old printers etc, then that will be when the "every scenario" scenario comes into play.
