Samsung has started rolling out a new firmware update for the Galaxy S III in the United Kingdom that fixes the Exynos security exploit and the sudden death issue.
The Exynos security exploit was discovered in the middle of last month, and allowed any malicious app to gain root access to the RAM/physical memory of any Exynos 4 device easily. Samsung was informed immediately about the security exploit and the company announced that it will roll-out a fix for the exploit as soon as possible.
The new firmware update (XXELLA) for the Galaxy S3 is still based on Android 4.1.2 Jelly Bean, and does not bring any new feature like the previous firmware updates brought with it.
While Samsung has not confirmed it officially, SamMobile have managed to confirm it with their sources that the firmware update also fixes the sudden death issue plaguing the Galaxy S3. Apparently, the firmware update also contains a new bootloader update that fixes the issue.
As of now, the firmware update is only live in the United Kingdom and is available via OTA or KIES. Giving how serious the security exploit and the sudden death issue is, expect Samsung to start a global roll-out of the update sometime soon.
