Since last year, there have been countless discussions about the Exynos exploit, which apparently allows device to be rooted easily using a single apk file – through a process commonly known as Exynos abuse among the Android community. The Exynos exploit however, will also allow malicious applications to easily infiltrate almost every device that run on the Exynos chipset which include the Samsung Galaxy S2 , Galaxy S3 and Galaxy Note 2.
Glad to say, AT&T has finally rolled out the latest OTA software update for the Samsung Galaxy Note 2 which will help to fix the vulnerability issue. The software however, will still remain at Android 4.1.2 Jelly Bean. If you’ve yet to receive the update from AT&T, you can go to Settings > About phone > System software updates to manually check for the Jelly Bean update.
Have you updated your Galaxy Note 2?
