GPS finds my current location a bit slow (about one minute, I live in İstanbul) No vibration for calls (only a small tic at the beginning) "Problem with network" notification message showing after received and missing calls Sometimes cellular data option not available to enable Calendar doesn't show Google and Facebook events (birthdays actually) There's already a way: How do I cancel tutorial? A way to skip tutorial app would be nice (I've only done three new installations, but it's still time consuming. It would be useful for ports without OTA support )
