Samsung Galaxy S 3 and Samsung Galaxy Note 2 by US Cellular will finally be updated to the MB1 build. This includes a few improvements and additions to the present build and promises an upgrade to the latest Android Jelly Bean.
The S 3 will most possibly have some bugs fixed and a few enhancements on audio during streaming. There will also be some additional capabilities for the camera, which will appeal to those who love continuous shooting.
On the other hand, there is no information given as to what upgrades or additions will be provided to the Note 2, since it already runs on the latest Jelly Bean. Also, it should be easier to flash Samsung devices when the update finally goes over the air. As such, always back up your phone and ensure that you got your phone's version correctly prior to downloading anything.
