They’ve just officially announced Android 4.1 Jelly Bean with tons and tons of changes. We mentioned a few in the announcement post linked to below, but they keep unveiling new awesome features you’ll want to hear about. From smooth as “butter” UI improvements, offline dictation, and some sweet improvements to widgets.

Widgets now will replace app icons on screen as you move them around. If there isn’t room, Jelly Bean makes room for you. It will automatically replace the icons on another homescreen. Automatic resizing has been improved, and if you’d like to delete a widget just swipe it off the screen — no more going to the dedicated trash area.

Voice dictation has just got even better with a feature we’ve all been dying to get — and that is offline voice dictation. Google’s awesome voice dictation introduced to Android 4.0 ICS has been completely improved in Jelly Bean. It’s more accurate, faster, more responsive, and offline mode makes it even better.

Just like multitasking with Ice Cream Sandwich, swipe to clear tasks has been brought to the gallery. As you view your photos in Android 4.1 Jelly Bean you can simply swipe up to delete the image. Don’t worry though, there is an undue button for those who are accident prone. Stay tuned as we continue to update as the details come out live.
