Today Samsung announced that its Galaxy Tab 2 tablets and would receive Android 4.1 Jelly Bean updates. Samsung, rather than including only cosmetic or back-end changes that you'll never actually see, has added a number of useful-sounding (that's a Youtube video link if you'd rather not read any further) features.
Most of the new features, like improved S Pen support, look to only be compatible with the Note 10.1, not the Tab 2 tablets. This update is so far only available for the Wi-Fi versions of the tablets.
A Samsung rep detailed what should be the biggest takeaways from the update. I've outlined them directly below, but keep reading if you seek more detail. I've not yet had a chance to test these out, so this is all according to Samsung:
-Improved side-by-side apps: Before you could run only two side-by-side apps. Now you can run as many windowed, resizable, and cascading apps at once as you can fit on the screen.
-No more lag when switching between windows.
-Improved S Pen support: Hovering the pen in apps like calendar, Web browser, and e-mail now previews information.
