[Samsung Galaxy Nexus] CPCookieMan:
In my experience the screenshot function is not working. I get a could not save message in the notification bar. Looks like there's two problems here, one that it couldn't open libwvm.so, and two that permission was denied I presume to the SD, which is maybe something to do with the new 0 folder setup.

Relevant logcat excerpt:
