trying to use mtp with my nokia 5800 xpressmusic. import tools windows opens then "connection fails" then i retry then "connection fails" with dolphin i can access to camera:/MTP device/ i see the contents but when itry to access to any folder camera:/MTP device/x/ then contents is not displayed see my bug report bug #307830 Reproducible: Always
Reopen this if still valid, Nexus7 seems to work just fine over MTP.
