lol, I still get annoyed by this.

I have turned off auto-rotate and set orientation to portrait. Now when I want to make a call I use the phone shortcut. If the keyboard is open the the application opens in landscape but as soon as I close the keyboard everything stays in potrait until I end the call. If I am in the contacts screen and I want to edit a contact I open the keyboard and contacts are displayed in landscape.

If I access the call functions via the the contacts shortcut contacts open up in landscape. If I then call someone with the keyboard closed the screen rotates to portrait. If I call someone with the keyboard open the call stays in landscape mode even if I then close the keyboard and hold the phone to my ear. When it comes to finishing the call however the display quickly changes to portrait so moving the end call button.
