In addition, because the bootloaders were also updated for the first time since the phone shipped, there is some hope that the new firmware also takes care of the "sudden death" issue that had been affecting some Samsung Galaxy S III owners. Earlier this week, Samsung said that the issue was caused by a firmware bug and that a firmware update would be sent to repair it.
As far as the exploit problem is concerned, the large number of devices that are potentially affected means we should see plenty more firmware updates from Samsung for quite a few regions. The models affected include the Samsung Galaxy S II (GT-I9100), Samsung Galaxy S III (GT-I9300), Samsung Galaxy S III LTE (GT-I9305), Samsung GALAXY Note (GT-N7000), Samsung GALAXY Note II (GT-N7100), Samsung GALAXY Note II Verizon-Locked Bootloader (SCH-I605), Samsung GALAXY Note 10.1 (GT-N8000), and the Samsung Galaxy Note 10.1 (GT-N8010).
Those who receive such an update should install it as soon as possible to protect their device.
