It seems like Google has "tiptoed-ly" launched a sneak attack to iOS and Windows Phone by launching the newest Android 4.1.2 (Jelly Bean) update. The refresh is rolling out all over the world for the Google Nexus 7, so expect the other Nexus devices and Motorola Xoom to receive the delight.
Conventionally, the update promises to fix some bugs and boost performance. However, it is a breath of fresh air to know that Nexus 7 can now have a landscape orientation in either lockscreen and homescreen.
Aside from the said tweaks, Google gave limited information about future Android updates. But Google Groups advices those Nexus 7 owners to update to 4.1.2 as soon as possible. File size is 31.3 MB.
