Verizon has confirmed in a statement to Android Central that the Android 4.1.2 update for the Galaxy S3 has been halted, and a fix is in the works following a number of complaints over connectivity and battery life. The VRBMD3 update, heralded as a "major" release that brought a bit of functionality seen in more recent releases -- multi-window and multi-screen, to name two -- sparked a number of threads in our Galaxy S3 forums of folks experiencing issues, and word of a fix started trickling out last week.
Here's the official word from Samsung:
A software update was recently pushed to the Samsung Galaxy S III, and while a majority of customers downloaded and installed the update successfully, a small number were negatively impacted. As a result the software update push has been postponed as a precaution for customers. We will notify them when a new software update is available for download.
So, everybody hang tight for an update, which hopefully will come sooner rather than later.
