Looks like Samsung wants to update most of its Android devices to Android 4.2.2 in this week. After updating the Galaxy S2 Plus and the Galaxy Tab 2 8.0, it's Galaxy Note 8.0 LTE's turn to get updated to Android 4.2.2. You might not be able to update your device to Android 4.2.2 Jelly Bean right away as the update is rolling out in phases. Currently, the Android 4.2.2 update has been given to the UK customers, but don't worry other countries will follow soon.
You can update your Samsung Galaxy Note 8.0 LTE (GT-N5120) through Samsung KIES or via OTA. Make sure you fully charge your device’s battery before upgrading as the update is quite big.
