Good news to owners of the LG G4 on the AT&T carrier, as now they can finally see the Android 6.0 Marshmallow roll out to their device.Thus far, LG has been quite consistent in its timely roll outs of the Marshmallow firmware update to its G4 handsets. This new Marshmallow roll out comes just a few days since the company pushed out the update to LG G4 users on the US Cellular, T-Mobile and Sprint, with users in Europe, Korea and Canada also having already received the upgrade to the latest OS from Google, and now it looks like AT&T is next in line. The update that comes weighing a size of 971 MB will raise the version of the device's software up to H81020n.Though Android 6.0 Marshmallow does pack a whole lot of visual enhancements, it does come with a slew of handy features that are better than what you'd get from an older OS. For example, users can make use of the reliable Google Now on Tap which primarily adds the Google Now functionality to virtually every corner of your device. Also included is an advanced app permissions control system, a killer battery saving feature called the Doze Mode, Android Pay accessibility and so much more.The update will probably take a couple of days to reach all the G4 handsets, but in case you want to manually check the update's availability status, go to Settings >> About phone >> Update center >> System updates >> Check for update.
