There have been many widespread reports about this phone, but so far it seems that the international model - i.e. any country not from North America is the only one with the issue.
The shutting down for no apparent reason and not restarting thereafter, or “Sudden Death” issue has been reported on popular forums and on various tech news websites, and popular Android website XDA-Developers, which has more than 150 pages of posts where people have reported the same problem.
But there is some good news! A few hours ago a Dutch website Tweakers reported that a Samsung spokesperson has said: "The problem seems to be affect a “limited number of Galaxy S3 models with 16GB memory,” and it’s caused by a firmware bug."
A fix for this bug is luckily software related, but at time of writing the release date for the patch which resolves the issue is not available.
Samsung has admitted the fault is theirs, and with the upcoming patch to resolve the issue, we shouldn't see any more of this in the future. Rest assured if you are victim to this bug and have a bricked S3, you should be able to organise a replacement or a fix through the warranty.
