If I am using a landscape app, double click the home button and then close it, the screen become a mess, everything is upside down and can't close any other app. Is this happening to somebody other than me?? I have an iPhone 7 and iOS 10.0.3
I've had a similar thing happen, but I don't remember exactly how to reproduce it. It doesn't freeze up my phone or anything though. It's just like the task switcher gets confused by the orientation swap.
