U.S. carriers roll out Galaxy Fold & Galaxy S9 November security patches, Exynos Note 8 also gets it

U.S. carrier-locked variants of Samsung Galaxy phones are always trailing their unlocked counterparts sold elsewhere when it comes to receiving software updates, minor or major OS upgrades.

The Galaxy Note 10 Android 10 update, for instance, has only arrived in the U.S. a few hours ago yet those in India have already picked up their brand-new One UI 2.0 beta update.

Granted, the stable Android 10 update will hit the Exynos-powered variants in Europe and other markets before arriving on the carrier-locked models in the U.S. powered by Qualcomm’s Snapdragon chipset.

In the same line of argument, the Galaxy Fold and Galaxy S9 picked up their November security patches in Europe a while ago, but it’s only now that the same updates are arriving in the U.S.

The update is rolling out to the Galaxy Fold as software version F900U1UES2ASK1. So far, AT&T, Sprint, and U.S. Cellular have already updated their software trackers with the latest version, with the changelog mentioning no more than the new security patch level.

Even though Verizon Wireless hasn’t updated its Galaxy Fold software tracker, a quick look at SamFrew reveals that the new firmware is available for the Verizon Galaxy Fold as well as several other channels.

Unfortunately, the T-Mobile firmware is still nowhere to be seen nor is the OTA update. Apparently, if you have a T-Mobile SIM in your Galaxy Fold, inserting an AT&T SIM, for instance, will summon the new OTA download.

T-Mobile will not serve up this update currently to the Fold. In my case, I just stuck in the provided ATT sim I had from purchasing my Fold and it served up the update immediately and then I put my T-Mobile SIM back in.

As far as the Galaxy S9 and S9+ are concerned, the November security update is arriving on T-Mobile, Sprint, Virgin Mobile and several other carriers in the U.S. Some will get the update as build number CSJ6 (T-Mobile) while others will get it as build CSJ7 (Sprint, Virgin Mobile, etc.).


T-Mobile has already updated its software support pages for both the Galaxy S9 and Galaxy S9+ and we also expect other carriers to do so in the coming days.

Elsewhere, the Exynos-powered Galaxy Note 8 is also receiving a new November security update as software version N950FXXS8DSK1. The update has been spotted in Panama and Trinidad & Tobago, with more regions expected to receive it in the coming days.
