If you’re ever tried to use a USB stick or external hard drive with your brand new Galaxy Nexus, you’ve no doubt faced difficulties. Despite supporting USB On-The-Go, Google has disabled automatic mounting of mass storage devices for some unknown reason.
Similar to the growing pains in previous versions of the OS, it is safe to assume that a first-party fix will eventually be coded into Android itself. In fact, Romain Guy has indicated that this functionality will be added in a “future release.”
Until then, however, we have XDA Senior Moderator and Recognized Developer Chainfire to rescue us from the dungeon of arbitrary limitation. StickMount allows rooted users to automatically mount and dismount USB mass storage devices.
For some reason the current Galaxy Nexus build (writing this on December 19, 2011) does not automatically mount mass storage devices (such as USB sticks) so you can use them from the phone.
Maybe Google will fix this soon, maybe not. Until that time there is StickMount !
If you’re rooted and looking for some automatic USB lovin’, head over to the original thread to get started._________
