The LG G4 operating on T-Mobile US can now download a fix for the "Stagefright" exploit. The update is available both over-the-air and through LG Bridge, and pushes the software version from 10H to 10N.

In addition to patching "Stagefright", this update also adds a Slow Motion option for video, and separates notification sounds from the ringer sound in Settings. The update is pushing out now, but may take a day or two to appear on your phone. If you want to check manually, you can head into your phone's Settings and check for the update.
