Most Mogul owners are reporting that it is fairly snapping when rotating the screen. There are some we have reported otherwise out of the box. And there are some that have reported this after using it awhile.
For those who have this happen after a while it is more than likely due to 3rd party software plugins on the Today page or really low on memory.
If it is a memory issue than use
Oxios to clear up your memory (it is free) and get it back with a simple click of a hardware button (if you map it to a button) or a tap of a button if you have it on your today screen.
If you have a lot of today screen plugins or only some plugins loaded with tabs and icons, this will do it too.
