How to update Galaxy Note 8 to latest October 2017 security patch?
Samsung Galaxy Note 8 becomes the third device to receive the latest October 2017 security patch. It also becomes the first device to receive Android 7.1.1 Nougat based on the latest Samsung Experience 8.5. It received the Blueborne vulnerability fix in September but still runs on August security patch. Today, the Chinese variants of Note 8 with model numbers SM-N9508 and SM-N9500 received the October security update. This means, the international and unlocked USA variants like SM-N950F & SM-N950U shall receive the same anytime soon.
According to the S8’s latest update, the October security patch brings stability to DeX mode. The DeX mode allows Samsung users to get a desktop-like experience on their phones and tablets. It also upgrades the Note 8 Launcher version to a newer one for more stability. Other updates are general device stability and bug fixes.
For the China and Hong Kong variants of Note 8 with model numbers SM-N9508 and SM-N9500, the firmware build numbers are N9500ZCU1AQJ1 and N9508ZMU1AQJ1. Currently, there are 3 firmware available for Note 8 global variants, viz, N950FXXU1AQIA, N950FXXU1AQI1, and N950FXXU1AQI8.
