Looks like the LG G4 isn’t the only T-Mobile device getting an update today.

T-Mobile says that its version of the Samsung Galaxy S4 is getting an update starting today, August 31. The update bumps the S4 to baseband M919UVUFOH3 and includes a patch for the Stagefright vulnerability.

This update weighs in at a paltry 15.37MB, but the fix that it includes is a biggie, so any of you that might still be rocking a Galaxy S4 should try to grab it as soon as possible. To check for the update, head into Settings > More > About device > Software update.
