The long-debated Exynos versus Snapdragon battle may never come to an end, albeit the latter is undoubtedly better performer than Samsung’s in-house silicon. However, Exynos models are not tied with carriers, thus the delays in software updates are quite negligible for them.

Galaxy S9+-August-update
Exynos Galaxy S9+ got August security patch a few days ago

Matter of fact, the cousin of Galaxy S9/S9+ aka Galaxy Note 9 also got the August security patch with the build identifier CSG5. As you can speculate, only international variants received this OTA, while US phones are still rocking the July patch.

The carrier unlocked US Snapdragon Galaxy Note 9 took the pole position to grab the July update, followed by carrier branded models such as AT&T, T-Mobile, Verizon and Sprint. As an addon, the wireless carrier also bundled camera night mode in their build (CSGA).


According to recent reportings by T-Mobile Galaxy Note 9 owners, a new incremental OTA is appearding on their phones. The build tag is slightly newer (CSGB) and the size of the update is less than 200 MB.


That’s a pleasant surprise! Within a week, T-Mobile is pushing a new OTA containing most up-to-date security patch! The bootloader version remains same (v2) though, and the ‘S’ letter (N960USQS2CSGB) confirms that no major changes are being done in this build.

Wait, there’s more to it. Besides T-Mobile, both Sprint and AT&T are rolling the same CSGB build with August security patch for Galaxy Note9. Due to staged distribution model, the OTA may not instantly show up on your phone, but you can use tools like Frija to download them manually.


Note 9 ATT August security patch ready

Just got it this morning in Texas.


Interestingly, we are unable to locate any such info from Verizon community. Their OTA tracking page is pointing towards the CSGA aka July update as the latest one. The unlocked variant is also lagging this time.
