T-Mobile LG V30 update brings Always-on display enhancements3
The folks over at TmoNews report the 715MB update adds the October security patch and some changes to the Always-on display feature. Basically, you'll be able to see more stuff on the display after the update, but you'll also be able to change the colors of the clock.
You can find new options in the Always-on display settings menu, so make sure to experiment with them after applying the update. The update is rolled out in waves, but you can go ahead and try to manually pull it on your LG V30 from the Settings / General tab / About phone / Update Center / System updates.
