T-Mobile Galaxy S9, S9+, and Note 9 now receiving updates


A trio of Samsung phones are now receiving updates from T-Mobile.

The Samsung Galaxy S9, Galaxy S9+, and Galaxy Note 9 are all being updated today. The Galaxy S9 is getting a 524.55MB update to version G960USQS4CSC8, the S9+’s 526.00MB update bumps it to version G965USQS4CSC8, and the Note 9 is receiving a 177.61MB update to version N960USQS1CSD1.

As for what’s included, all three phones are getting the April 1, 2019 Android security patches. The changelogs for the updates don’t mention any other changes, so it’s unclear what else might be packed inside.


TmoNews readers Casey, Maciej, and Debjit all received these updates this morning, so if you’ve got a Galaxy S9, S9+, or Note 9, you should see the update on your phone soon. You can also check for it manually by going into your Settings app and selecting “Software update” followed by “Download updates manually”.

Once your Galaxy S9, S9+, or Note 9 gets its update, be sure to let us know if you spot any changes!

Thanks, Casey, Maciej, and Debjit!

  • I sure hope this fixes the camera and battery bugs a number of people have noted.

    Will this finally fix the stupid RCS issues?! Unacceptable that texting is an issue on a flagship phone in 2019.

    Wasn’t the –CSC8 update announced back in January? Still hasn’t shown up on my S9

  • Jay Holm

    Seems the LG G7 is never going to be updated?

    As a day one S9+ owner I can say I’ve been satisfied with the security updates. They’ve been very consistent.

    If anyone has the Galaxy Tab S4 (wi-fi version), Samsung is pushing the Android Pie update. Mine is downloading now.

  • jkchaffee

    I lost all connections to Internet after the update. I cannot even get to T-Mobile app

    …..and still waiting for the ….CSC8 update. I have attempted multiple times manually over the past several days, only to get a “network server failure” every time. WUWT? Samsung Galaxy S9 U1 unlocked edition.

    Has anyone heard about an issue with S9+ at tmobile? I am still stuck on July 1 security patch. I have spoke to TMO and Samsung and both have been of no help.
