As a late Christmas present this month, the Android 4.1 Jellybean update to the Samsung Galaxy Tab 2 has finally gone out. I got mine updated earlier this week and have had a few days to play with it. The most obvious features in the Jellybean update are the new voice search (a Siri-like interface that doesn't talk back), the ability to dictate while offline and the introduction of Google Now, which is Google's attempt to predict what you'll need and get it to you before you even realize you need it. The theory is that your device should learn your habits and interests over time and will then be able to offer relevant traffic, weather and point-of-interest information.
Users of the Samsung Galaxy Tab 2 like myself who have gotten used to having the screenshot button on the dock are going to be a little miffed that the screenshot button has disappeared after updating to 4.1. Not to worry. You still have a few options to get it back. You can still take a screenshot by holding the volume-down and power key at the same time. You can also add the button back by going to your Display settings and messing with your quick launch buttons.
All things considered, the Android 4.1 update for the Samsung Galaxy Tab 2 has added a lot to the device with a minimum of hassle.
