Ok, here is my experience... I updated my phone via "Nokia Software Updater". After that, I opened the "Phone" app, and it started in landscape mode, so I decided to go to options, and I turned of the "turning" and put it as "portait" as defualt. After that, I closed the app, and open it again, and it opened in landscape mode again. After playing with the setting, the turning is still working and it always starts in landscape mode. Once I get a important call, I will reboot my phone and update about the problems.
