Just an idea for a future update free to steal. I'm laying down with my phone in my hand and once it senses that Im holding it horizontally the screen shifts. I then manually hit the screen position lock button to view properly. What if the same or similar tech that recognizes my face to unlock screen activates as phone senses the screen is horizontal and then notes the position of my eyes. Therefore prompting the phone to react not merely to its position in space but to my faces corresponding position. So Im laying down and pick up my phone and just as it wants to turn wide screen it tracks my eyes and remains in default. And vice versa if i do indeed want to view widescreen while lying down. Of course you can have the option to lock in case you have a reason (cant think of one) and could turn this feature on and off in settings.
