T-Mobile has finally begun pushing out the Marshmallow update for the LG G3. We've already seen the other major U.S. carriers push the update out, so it's great to see T-Mobile join that party. The update brings a number of big changes to the phone, such as Doze, enhanced permission controls and more.
T-Mobile's change log doesn't note much beyond that the update brings some Wi-Fi calling enhancements along with Marshmallow. You should be able to grab the update over-the-air now. If you aren't seeing the update notification, head into your Settings, About Phone and finally check for the update. Be sure to let us know how the update works out for you!
