T-Mobile has started rolling out a new update to LG G4 units on its network. Arriving as software version H81120r and weighing in at around 90MB, the update brings along Android security fixes for the month of January. Sadly, the update is still based on Marshmallow (version 6.0.1), meaning those waiting for the Nougat update are currently out of luck. Aside from the latest security patch, no other changes are included in the update (at-least that's what the T-Mobile LG G4 webpage reveals). Source
