Put this on my tablet about a week ago and I am very glad I did. At first I jumped through a bunch of hoops trying to get the VZW update to 4.0.4 and that never worked. I finally gave up and put CyanogenMod 10.1 which was tailored to this tablet which gave me Android 4.2.1 and then downloaded the apps I like and all is doing well so far and I don't really expect anything really out of the ordinary. I just read that Samsung is updating the International version of the 7.7 to Android 4.1.2 which is the one on my phone Samsung Galaxy SIII which since they have a new version of this ready for download for my phone I may put that on my phone as well. My version on my TAB is 10.1-20130105-NIGHTLY-I815 which I was warned about issues but so far I have not experienced any issues but I am sure some are there. I don't have this tablet on VZW, I just use it as WIFI because if I want it on VZW I use it off VZW from my SIII. YMMV
