If you own a Galaxy S9 or Galaxy S9+ on T-Mobile, there is a new software update available to download. The update, as expected, installs the latest November security patch alongside some bug fixes and performance improvements.
No new features included in the update
The November 2019 security patch for Galaxy devices includes a fix for a critical bug in the Android OS that was discovered in September. The Galaxy S9 was one of three Galaxy devices mentioned by name in the list of affected devices, so it’s only natural that Samsung would want to release the November update for 2018 Galaxy S flagship in every country as soon as possible. Hopefully, carriers in the US will show similar urgency and soon follow T-Mobile and release the update for their Galaxy S9 and S9+ variants.
You can check for the update manually, just go to the Settings > Software updates > Check for Updates. If your device finds a new software update, tap Download now.
