In the last few days suddenly apps such as RingGo and Google Calendar will flip to "portrait" view at times (the phone has not been rotated) - any idea what has caused this change?
Hmm. I have been using the "Force Rotate" option via the Planet App Bar.
It seems to remember orientation on a per-app basis. I use just about every app in landscape mode except for just a couple which only work well in portrait. When I use those couple, somehow Force Rotate seems to remember and those ones rotate to Portrait while others stay in Landscape.
However, for the last few days one of my portrait apps, Weather Underground, consistently flips to Portrait and I have to put it back to Landscape every time I open it. Before, it used to remember.
I don't know what has changed.
