The Galaxy Note 5 on T-Mobile is being updated to version N920TUVS4EQG1, equipped with the July security patch. Not only is the security getting upgraded, but system improvements and stability improvements are also listed.
The underlying Android build isn’t changing, though, with it still listed at 7.0+. And if you were wondering, it doesn’t seem likely that the Note 5 will be updated to Android O, but you never know. Still, security patch updates are always welcomed.
Note 5 owners on T-Mobile, go get that update.
