It looks like AT&T has finally gotten around to upgrading its Samsung Galaxy Note 2 to fix the security exploit that was found for Exynos-based devices. The exploit was discovered by members of the development community at the end of 2012, and it was identified by Samsung as a serious issue that the OEM looked to fix as soon as possible.
This particular upgrade brings the firmware version up to I317UCAMA4, though we’re still on Android 4.1.2 here. It’s a small little guy, as well, as it’ll only eat up about 8MB of bandwidth. It’s an upgrade you’ll want to apply as soon as possible, so if your phone notifies you that it’s ready to be downloaded and installed be sure to take care of that. If you don’t get the notification then there’s a high chance you’ll find it upon hitting the software upgrade menu under Settings > About Phone.
Even though the upgrade is small, you should still make sure your WiFi is turned on and battery is charged to at least 50% before applying it just to make sure nothing goes wrong. Take care of all of that and you should be well on your way to a more secure device. Be sure to read our earlier post about the exploit that today’s upgrade is targeting to get an idea of how important it is.
