This happens enough times to be really annoying, but sometimes when I unlock my iPhone 8 Plus, the home screen rotates to landscape even though it's not in a landscape orientation. It forces me to hold the phone up straight to get it back to standard. I can't really reproduce it. It seems to just happen at random. Anyone else have this bug? Obviously I could lock the screen orientation but then I'd have to unlock it every time I want to watch a video, which would probably be more annoying. This is with iOS 11.1.2, although it happened in previous versions too.
