Thank for any input information!
If you want to lock and unlock the rotation pdf view and another apps use this guide: xwTweak 0.1.0 - Global Accelerometer Switch
More useful patch for pdf view I've known:
1. Hide Header patch: [PATCH] Hide Annoying Header In PDFViewer (tarirene) (useful in the landscape mode)
2. Hide Page count patch by tarirene: [PATCH REQUEST] PDF View Improvements
It's better for lager view on Pdf view.
And for who installed both patches: Pdf view will not display full screen (there is a black bar at the bottom). You can sold this problem by using the document-assistant2.zip
