In addition to this, Samsung confirmed that the Wi-Fi Galaxy Tab 2 7.0 sold in the US is also being updated to Android 4.1. Actually, a number of owners should have received the new software already since it has been available for several days now.
Not to be forgotten is the US version of the Wi-Fi-only Samsung Galaxy note 10.1, which has started receiving its dose of Jelly Bean as well. However, the tablet is not only being updated to Android 4.1, but it is also receiving the Premium Suite pack of goodies featuring a fair dose of tablet-specific UI optimizations and new applications meant to take advantage of the S Pen.
In case your Samsung Galaxy Tab 2 or Note 10.1 has not been updated yet, a notification will inform you as soon as the new software is available. Alternatively, you can perform a manual check by going to "Settings > About Tablet", where an "Update" option is present.
