Samsung Galaxy S8, S8+, and Note 5 receive new update, brings security improvements

T-Mobile is the first US carrier to provide the patch for Samsung's 2017 flagship pair. After installation, the build number for the T-Mo versions of the Galaxy S8 and S8+ should be at G950USQS2BQL1 and G955USQS2BQL1, respectively. South Korean users have also reported receiving the same update, and we suspect that a more global rollout will occur in the following days.

Meanwhile, the Galaxy Note 5 is also receiving a similar update. With a size of 17MB, the update brings small improvements to performance, stability, and bug fixes in addition to the aforementioned security patch. 

When you get a notification for the software upgrade on your handset, make sure that your phone is sufficiently charged and connected to a Wi-Fi network before proceeding. If you haven't received one already, you can check for the update manually by heading to Settings > About Device > Software Updates.
