It looks like T-Mobile LG G2 owners aren't the only ones getting some Lollipop love today, as AT&T has also started pushing the update out to the handset over-the-air.
The update started rolling out today, and brings the LG G2 up to Android 5.0.1 Lollipop. Of course, the update brings all of the usual Lollipop goodies such as a new multitasking UI, revamped notification handling, and a heavy emphasis on Google's Material Design.
As far as size is concerned, this update clocks in at 721 MB large and you'll need a WiFi connection handy to pull it down. As AT&T just started rolling the update out, it may not have hit your device yet. To check for it manually, all you have to do is head into the settings menu and navigate to General > About Phone > Software update > Update Now.
